Do you guys know how can we use UPF in Workbench? I download the UPF extension and I read the. Recently, I started working with UPFs. Right now I chiefly work with UPF-functions , however, I want to use UPF-subroutines soon.

Windows Installation Guide lists the compilers that are required for Windows systems. These messages may state that object files have been created, but the Mechanical APDL executable has not been created; or the errors may state that some libraries necessary to complete the link cannot be found. Visual Ansyd Professional Update 4 is also required for linking user programmable features on Windows platforms. After you have selected all desired user routines, press Enter to quit.

UPF: Chapter 1: Using User Programmable Features (UPFs) (UP)

If you are running in a distributed memory parallel environment Distributed ANSYSyou must include the name of the master node when specifying the working directory:. This requirement is due to shared library usage. If you modify any of the user routines, move them to the folder s they are linking in.

The format of the command is:. A script named findUPF.

The user programmable features are loaded onto the system only if you perform a custom installation and choose to install the customization tools. Output from a user-linked version contains the following statement: If the test worked correctly, this should display many lines of debug from all output files.


There are three methods that you can use to link your custom uppf into the Mechanical APDL program:. The source files for the user routines reside in the following subdirectory: The executable file s created will be named ansys.

After relinking the ANSYS executable, the program can be executed by either of the following two methods:. When you run a user-linked version of the program by this method, the output includes this message:. Select ufp desired options then pick Run to execute the customized ansys. The routines that have been linked will be included in the output listing. The following user routines can be linked using this method:. You must include the path to this script in your system PATH variable.

This procedure will ask which versions you intend to relink and then will compile all Fortran files files ending with. The -custom option must be the last option at the end of the command line. Before using any of the upff described below for linking UPFs, open the following Command Prompt window if you have Visual Studio Professional installed:.

These snsys usually indicate that required compiler environment variables are not set. Enter the user routine name you wish to include. When creating custom executables, they must be named ansys.

Compiling and Linking UPFs on Windows Systems

Note that when using a combination of languages, you are responsible for the calling interfaces between languages see Programming in Languages Other than Fortran. Use the following command:.


When the job is complete, run the following commands from a Command Prompt window:. ZnsysC files files ending with. You will need all the compilers specified in the Installation Guide specific to your operating system to use these user programmable features. The specified routine must reside in the current working directory.

Get UPF return value from Mechanical APDL input file

To execute the relinked ansys. Create a dynamic-link library. Output from a user-linked version contains the following statement:. The user routines that are supported by this method will appear in a list. All Fortran files files ending with.

This is a simple, automated test that verifies whether compilers are correctly installed and configured. In this command prompt window, issue the drive letter and all the necessary cd commands to move to the directory where the customized files exist example: The procedure then loads all object files files ending with. The first ulf of the output is shown below:. If you are running in a distributed memory parallel environment Distributed ANSYSyou need to include the name of the master node when specifying the working directory:.

By default this folder is:.
