  Installing ANSYS was a nightmare and now that It's been installed has been breaking every other week. nThe default port (1055) on the license server is not default and Ansys server keeps opening random ports above 50000. After having this issue multiple times now, nI'm just a student trying to use ANSYS for some research. I do not have access to the server machine, nor do I have the expertise to answer any questions regarding how the server machine is setup. I have created this post to that others can know to have their technical support try looking for undocumented ports via lmutil commands.nIf anyone knows why this happening, please take some time to bestow it upon me. n

  The ansyslmd port is dynamic by default, running on any available port. The lmgrd port is by default set to 1055, but can be changed by the person managing the server. They can also set ansyslmd to a static port by adding PORT=XXXXX on the VENDOR line of the license file, where XXXXX is their chosen port. This would then allow any firewalls to be opened to the necessary ports.nnThanksnMattn
