How are the total workspace (-m) and database (-db) memory sizes set in WB Simulation?

In WB Simulation Release 11.0, the database memory is based upon the number of nodes and DOFS per node. The requested database memory size is intended to limit the amount paging required. The...

I would like to make the angular velocity in a rotational speed be a function of the torque so that it is adjusted
until the torque reaches a desired value. How can I do this?

<br><br>You can let the angular velocity of a rotating domain be a function of the torque exerted on one of the rotating components. It's best to do this with a User CEL...

In Simulation, the "Export Branch to Shortcut" is not displayed in the Insert menu (context menu) choices. Why?

A known bug exists in 8.1 and 9.0 whereby a CAE Template license (CAETMPL) is required in order for the "Export Branch to Shortcut" choice to be displayed.<br>This is not the...

When trying to use ANSYS Workbench DesignModeler to view an existing model's geometry I get the following script error message and I can't use DesignModeler at all:

Script Error:
Line: 13389
Char: 12
Error: Path not found
Code: 800a004c
Source: Microsoft JScript runtime error
ag.fs.CreateFolder (new_path);

This is caused by specifying an invalid directory for the temporary files from Workbench 8.1. To reset the directory to a valid one start ANSYS Workbench 8.1 then select (from the bottom left hand...

How can I determine which version of Workbench Environment created a dsdb file?

Resume the dsdb file in any version of Workbench, then run the macro,<br>ShowFileVersionMacro.js, from Simulation's Tools-Run Macro menu.<br><br>This macro file is located...

Customer gets the following errors when trying to start Workbench8.1 on a linux machine with ./startpage command:

Initialization Error!
The product is not installed correctly!

Output in the xterm window when trying to start CFX 5:

What is causing these errors?

This is a problem with WB on Linux machines that has been fixed at WB 9.0.<br><br>There are two methods to get around this problem:<br><br>1) Move /usr/bin/regsvr32 to...

I am trying to run a job in parallel using MPI (two cpu's). Up till now, without success. After installing the service, registering the identical user on both computers, it still fails to launch process 1, because the LogonUser failed - the message is:

Failed to launch Process 1:

LaunchProcess failed, LogonUser failed, Logon failure: unknown user name or bad password.
aborting ....

Our login name is (xxxxx) but the password is empty. (We only have to hit return to enter the system.) Does this lead to problems?

For this error, the CFX-5.7 Installation manual says:<br>"The user ID specified via register-mpich-user is not valid for one of the hosts in the run.<br>To find which host,...

Customer downloaded the Linux version of ANSYS 8.1 onto a cd, then mounted it and ran the INSTALL. He then gets the following error:

[root@sgi350 ansys_inc]# ./INSTALL -NOGUI

: bad interpreter: No such file or directory

Why isn't he able to successfully install from his cd?

Bad interpreter messages are always permission problems or the path to the shell (first line of script) is not pointing to the<br>shell interpreter. The customer should do the...

In ANSYS Workbench Environment (AWE) 8.1, is possible to import a geometry containing both solids and surfaces from Pro/E?
