  1. missing normal termination

    I'm having the same error with RADIOSS 2017.2.1 starter file. Has this issue been resolved yet? If so, kindly advise please. Thanks, Shawoon
  2. Hello, I'm running a RADIOSS incremental simulation; after simulation it doesn't write any .sta file. I've checked my engine deck where state file is option is defined: /STATE/DT 0.002375000000000 0.002375000000000 4 I'm attaching my engine deck file here. Can you please tell me if anything else I'm missing? Thanks, Shawoon modelC_0001.rad
  3. Pressure Analysis of a deformed gasket

    Hi @Prakash, I tried applying load through NLOAD before as you suggested; it didn't work. It came up with a different error: *** ERROR # 1358 *** Referenced ID 1 in NLOAD, but missing in BULK DATA. Do you think I need to create a separate NLOAD card in this case? Thanks in advance. -_Shawoon
  4. Hi, I'm trying to do a pressure analysis in a compressed gasket. I did a compression analysis of a gasket to generate a deformed gasket body using RADIOSS. Now, I need to add pressure on the selected areas of gasket in OptiStruc. I used MAT 1 with MATX 42 card for my material to run an nonlinear explicit dynamic analysis. But, I'm encountering this error message: *** ERROR # 4028 *** No load is defined in EXPDYN subcase 1. Looks like I'm not defining the load collector properly. Can anyone suggest me to resolve this error please? I'm attaching the model file to check. Thanks, Shawoon gasketdeformed.hm
  5. Error Output - Stack Overflow

    Turns out to be a problem related to the Antivirus & Firewall settings which wasn't allowing the RADIOSS solver to access memory in the system.
