Recently, I started working with UPFs. Right now I chiefly work with UPF-functions, however, I want to use UPF-subroutines soon.
With UPF-functions I manage to do the following:
- send messages to the output,
- calculate within the UPF-Fortran file, and
- return any variable value via text output.
Now I want to store the UPF-function's return value as parameter in APDL. Which APDL command does the magic?
As you can see below, I use a batch file (Code 1) to run a Mechanical APDL input file (Code 2) in batch mode. Within Code 2, user01.f (*) is set to be an UPF. For testing, I execute user01.f by issuing the command usr1. This command should be replaced by an appropriate one, storing the UPF-function's return value as parameter.I thought on something like *set,myParam,myReturn , but did not succeed up know.
Finally, a general question: Is the idea of calculating something within a function and handing over the result to APDL okay, or not acceptable at all?
(*) I copied the file to my working directory, which is available from \ANSYS Inc\v180\ansys\customize\user\user01.f (OS Windows). The code is also available in ANSYS Help Viewer (Go to (Ctrl+Shift+D) help/ans_prog/Hlp_P_UPFDEFCMD.html#c7K4r2c9lcd ).
