Hi,<\/p>\n

I am running a simple structural problem in Ansys APDL, this is done in batch mode and the command is given in Matlab. I created the setup in Ansys Mechanical, and saved an input file which I am running in Matlab with:<\/p>\n

<\/p>\n<\/p>\n

dos( "C:Program FilesANSYS Incv195ansys\binwinx64ANSYS195.exe" -b -i "inputfilename.inp" -o "outputfilename.out" -np 1 )<\/p>\n

<\/p>\n<\/p>\n

I want to perform an optimization process in Matlab on this simulation (using fmincon). Currently I've got this working correctly in serial mode. However, to speed up the optimization process, I want to perform this in parallel. The Matlab fmincon optimization solver is able to do this, and I already made sure that temporary input files are created for each evaluation (to prevent overwriting in parallel). However, somehow calling Ansys from Matlab in parallel mode does not work correctly. I get the error:<\/p>\n

<\/p>\n<\/p>\n

 *** ERROR *** Another ANSYS job with the same job name (file) is already running in this directory or the file.lock file has not been deleted from an abnormally terminated ANSYS run. To disable this check, set the ANSYS_LOCK environment variable to OFF.<\/p>\n

<\/p>\n<\/p>\n

I suspect that the problem is that there is a set of automatically-generated job files in my working directory, all named 'file.*' (including file.lock, see image below). In parallel these job files are used by multiple processes, which is not allowed. <\/p>\n
