MULTIEXTRACTOR CHANGE TEMP DIRECTORY SOFTWARE
This involves providing you with access to technical support and downloads of the latest software through forums such as the blog, discussion forum, and Application Exchange. The goal of COMSOL Access is to provide a forum for you to communicate effectively with COMSOL as well as your colleagues within the multiphysics simulation community. If someone in future founds this helpful, I am glad. Using such trick I was able to run COMSOL on cluster nodes with no problems (didn't need even -configure and -data options). Universal solution: make symbolic link from your main home directory, to your working directory, in my case: Failed as soon as wanted to start solver. Found some useful command line options (namely -configuration, -data), but that only got me till reading project file and compiling equations. Tried to persuade the COMSOL to use new home directory, with no luck. And after that action the directory ~./ is NOT writable, but IS readable (!). I am also using COMSOL (v4.2a) on cluster system, that change the home directory after assigning the node, namely from ~./ to ~./pfs. I know that the tread is quite old, but since I did not find this solution anyplace else, thought I would post it anyways, if someone searches for similar problem. You may need to delete the old recovery files to save disk space. cmd file, comsol will create a subfolder like D:\Temp\cs to save big temporary files such as mesh, solution, model files, and D:\Temp\hsperfdata_ to save other information, where is a five digit random number, is your real username.īy the way, the recovery files are saved in \.comsol\v41\recoveries. When you run comsol by double clicking on this shortcut or the. If you want, you can create a shortcut for this. So in order to save the temporary files such as the big solution files into another folder, we can change the system environment variable, tmp.įor example, if we want to save these big files into D:\Temp, we can create a dos batch file comsol_myrun.cmd in the folder where we can find comsol.exe, the main file to run comsol, the content of the file is as follows, See log file: nullĪfter trying several times, I find the solution as follows,Ĭomsol 4.1 temporary files are saved into the system defaut temporary folder, which is specified by the system environment variable of tmp.

However, Comsol 4.0a has some issues with it as it still tries to access /home/shakeeb/ which is no longer available. All applications I have used until now used to notice this change without any trouble. Although I just posted it to support, I will appreciate if there can be a quick reply here.įor some reason related to the organization of our linux cluster, I have to change $HOME from the regular /home/shakeeb/ to a new location /lustre/vol/shakeeb. I am having a problem which might sound familiar to people discussing the original topic.
