# When I try to distribute a run with HP-MPI in 12.1 version on 2 processors, I have an error message that says I need an HPC license

It's possible to distribute a solve on 2 processors without HPC license. The error message is due to a malfunction of the initial license manager. You need to install "ANSYS License...

# How can I activate the stress stiffening with 22x elements (SOLID223, 226 & 227) ?

We do not have SOLCONTROL for the coupled-field element that would automatically set SSTIF to on when NLGEOM is on.<br> So it's necessary to set SSTIF,ON to activate stress stiffening.

# Is it possible to borrow licenses for FEMGV 7.1? I have used the Run the ANSYS Borrow Utility option on the Client ANSLIC_ADMIN Utility and the licenses appear to have been correctly but when I detach the laptop from the network containing the license server I am not able to run FEMGV 7.1; it fails with a license error.

It is not possible to borrow licenses for FEMGV at this time. The FEMGV 7.1 software needs to be rebuilt to contain a correction for this. This has been requested.

# How do I create a domain interface when the two sides of the interface have the same mesh location? If you want to add an interface between two domains and do not want to use the automatic interfaces (maybe because you only want a subset of the faces) you will want to add named selections for the two sides especially if there are a large number of faces. This is ok if the domains are obtained from different parts at the meshing stage but if they are meshed within a single part the mesher will have a single location to represent both sides so the named selection will end up with faces from both sides of the interface so what is the easiest workaround?

1) Create the name selection on the joins, this will be loaded into CFX but will have faces from bodies on both sides of the interface (therefore double the number required).<br><br>2)...
