Hello, I have just taken a look at the case. Unfortunately library case Y302 involves ground coding and can not therefore run directly. I believe that it was only meant to be available for certain customers who had various metallurgical interests and who had purchased the ground coding. However It shouldn't be in the library list as it can not run without extra ground code.

It is also a case that involves lots of PIL conditional choices, so loading into the VR editor would overwrite these.

If this is a case you really want to run, I can give you the following advice. You will be able to run the case but it will not have all of the physics in it.

Use satellite to load the case, (i.e. runsat), this will keep the original Q1 structure. Then look at the Q1, it will contain boolean variables to switch specific heat and conductivity to constants, switch them to T. You will then need to comment the PATCHES that involve ground coding, these are LATIN, LATFIX and DARCY. The case should now run. However the code to implement DARCY resistance sources and Latent heat release in solid regions will have been removed and you would need to replace this with something (ground coding) of your own.

The DARCY resistance should be quite straight forward as this involves a large coefficient in the COVAL statement to stop flow in solid regions.

The Latent heat release will require you to set some source such as density*Lat_Heat*ds/dt, where s represents the volume fraction of solid.

Hope this helps

P.S. Also increase the LSWEEP, set LSWEEP=300 say
