Hi, we use STAR-CD v.4.02 and 3.26. When importing and checking .pat or .nas file to proam, STAR-CD v.4.02 uses very much memory (about 2 GB). When using STAR-CD v.3.26 this problem needs far less memory. Did anybody face this? Can anybody explain, why it takes place?

Thanks for attention.

it is normal. it is star v4. we have been recommended to use it only if really, really, really necessary. I don't think the chief software engineer of starv4 has done much industrial software in the past, only academic.

If I remember correctly, we were told in the '06 Detroit Users' Conference that STAR v4 is storing vertices in double precision. This doesn't mean that model size is going to double.
