The technique keeps all related macros inside one source file. An example illustrates. This complicates programming. This creates a one-file source macro that contains many sub-macros.

The vast majority of the simulations I run include many bolts holding the assembly together. Therefore, I would like to automate as much of the simulation setup associated with the bolts as I possibly can. I'm not sure if such a thing is possible, but I will describe what I'm doing so that you might be able to tell me what if anything can be automated.

Additionally, I am attaching a simple example of what I typically do. The mesh is always going to be imported from CDB files, and although there may be multiple files containing bolts, the files containing bolts will contain bolts exclusively.

Welcome to ANSYS Training

With " " starting at 1 with each CDB file and incrementing by 1 for each additional solid body that gets imported. I will be grouping the solid bodies from each CDB file together and naming the groups according to the CDB file's name.

Groups containing bolts will always include the word "Bolt" in their name. Coordinate Systems:.

Each bolt has a coordinate system associated with it. I have been naming the coordinate systems to be consistent with the number in the bolt's name e. Frictional contacts using a coefficient of 0. I would use ANSYS's auto-detection to generate these connections, but that has inexplicably caused my models to crash in the past, so I have started creating them myself. Named Selections:.Now I happen to think that APDL is straightforward to use for most of the things that I do, provided I have the documentation open to the right place.

The one thing that tends to stop me in my tracks, however, is arrays and tables in APDL. The information is spread out in multiple places in the help and it is just not something I do often enough to memorize. Yet arrays allow you to deal with vectors and matrices of data and are extremely useful for postprocessing.

Tables allow you to apply varying loads and properties in many places where you would normally apply a constant. Arrays are a good way to hold vector or matrix data. These can vary based on position, time, temperature and more.

Tables are how this is accomplished. As you can see, you can get some nice interpolation functionality very quickly. Just like arrays you can do this in up to 5 dimensions! If you intend to send a varying load or property later, this is where you tell it what it varies by. If you are like me, you may be slightly perturbed by the lack of units in the above plots.

This is intentional. These commands are unitless, just like APDL. Doing this will make sure that your unit system is consistent and will prevent several types of errors. Prestigious companies in Northern California turn to Ozen Engineering as the single-source of reliable simulation solutions.

Sureshv Suri.The ANSYS finite element solvers enable a breadth and depth of capabilities unmatched by anyone in the world of computer-aided simulation. Thermal, Structural, Acoustic, Piezoelectric, Electrostatic and Circuit Coupled Electromagnetics are just an example of what can be simulated.

APDL is the foundation for all sophisticated features, many of which are not exposed in the Workbench Mechanical user interface. It also offers many conveniences such as parameterization, macros, branching and looping, and complex math operations. With this foundation in place, users can apply this knowledge to efficiently set up, solve, and post process virtually any type of analysis.

Following completion of this course, you will be able to:. Comfortably navigate the Mechanical APDL user interface and apply a proven workflow for creating, solving, and post-processing 2-D and 3-D finite element models. If there is no active public schedule available, private training can be arranged. Please contact us. This is a 3-day classroom course covering both lectures and workshops. For virtual training, this course is covered over 5 x 2-hour sessions, lectures only.

Learning Outcome Following completion of this course, you will be able to: Comfortably navigate the Mechanical APDL user interface and apply a proven workflow for creating, solving, and post-processing 2-D and 3-D finite element models.

Use Selection Logic to efficiently operate on sub-regions of a model for meshing, loading, and post-processing. Understand the concept of element attributes and apply it to building effective, efficient meshes using beam, shell, and solid elements. Implement coupled-field solutions using 1-D fluid flow elements and 2-D and 3-D solid elements.

Prerequisites A technical education and a background in the fundamentals of finite element analysis are recommended. An engineering degree is not required.

It's fixed at the larger end and a lb force is applied at the smaller end. To obtain the Workbench project file. Before we create the input file, please check that the status of the pre-processing cells before the setup are complete Green check marks.

Go onto the Rescale platform, start and name a new job, and upload the input file that you generated from Workbench. You can either upload the input file from your local computer or from the Rescale cloud files. For this example, configure the software settings by selecting Ansys Mechanical version For more information on launching a basic job, please refer to the tutorial here.

The most common data reading needs include numbers from a two-column 2D table, or from a multiple-column 2D table. More complex data structures are possible, but not discussed in this document. This offers little flexibility. If the data comes from a 2-column CSV data table, it is assumed that the first column of the data table is intended for use in the Zeroth column of the Table Array, and that the second column in the data table is intended for use in the First column of the Table Array.

This can be seen in Figure 1 above. It is assumed that there is no primary or other variable for the Column positions when a 2-column CSV file is loaded, so no data is placed in the Zeroth Row of the Table Array. The dimension for the number of rows is the same as the number of rows of data in the CSV file. If data comes from a 3-column CSV file, or with more columns, each column is shifted one column to the left in the Table Array, with the first column of the CSV file going into the Zeroth column of the Table Array, and so on.

Users must be aware of this behavior. The dimension of the number of rows in such a Table Array can be reduced by onesince the Zeroth row will hold data.

In Figure 2, in the view of Table Array data on the right, the 0,0 position in the Table Array contains a numerical value, even though it is not shown. In this example, it contains 0. The number of commas must be the same in each row of the incoming CSV file.

The user has to know how many lines to skip in advance, entering the correct value. The user does not need to know how many lines are in the CSV file. One way to discover the number of lines in a text file is with the APDL command:. The argument numlines is the scalar parameter that will hold the number of lines in the file.

The user needs to know the number of columns in a row, and the number of rows to skip at the start of the file—this can usually be done discovered by visual inspection of the CSV file. From that information, the dimensions of the Table Array can be calculated. If the CSV file has two columns, then the dimensioned number of rows for a 2D Table Array must be the same as the number of rows of numerical data.


The number of columns must be one less than the number of columns in the CSV file. If the CSV file has three or more columns, then the dimensioned number of rows for a 2D Table Array must be one less than the number of rows of data. File name and directory path characters maximum, including the characters needed for the directory path.

An unspecified directory path defaults to the working directory; in this case, you can use all characters for the file name. File name has no default. The name of the previously dimensioned Table Array is supplied as the argument Par. Where to position the Table Array data in the numerical Array that receives the data depends on whether the original CSV file had two columns or more.

One line in the CSV file is to be skipped:. Enter the name of the CSV file below! Column 0 of 'mytable' will hold first column of the CSV file! Column 1 of 'mytable' will hold second column of the CSV file! Shift column to right. Note that the Table Array is dimensioned one less than the number of lines to read, because row Zero holds a row of data:. Column 0 of 'mytable' holds the first column of the CSV file!
