Hi all, Thanx for ur time and attention. I have created a cas file by appending two cas files and also created the interface (coupled) between them. When I try to open the new cas file, it gives the following messages:

Error: access: unbound variable Error Object: get-var

Error: CDR: invalid argument [1]: wrong type [not a pair] Error Object: #f

I have checked the original two cas files and there seems to be nothing wrong with them. can somebody give suggestions to overcome this. Thanx in advance. Sharma.

append case file can give spurious results due to differences in the cases. I would merge the meshes via utility tmerge or use TGrid then use file/write-bc and read-bc to apply the boundary conditions from the cases.

Thanx for your suggestion, will try and get back to you.
