CDH/AMLS and FastFRS new release

Dear AMLS/FastFRS user,

 

We are pleased to inform you that CDH/AMLS release version 5.2 and CDH/FastFRS 2.2 (rev. 188) is now available. The latest CDH/AMLS and CDH/FastFRS release version offer following enhancements and corrections:

 

CDH/AMLS - Enhancements version 5.2.r188 compared to 5.2.r179

 

  • DDB: added support for MSC-Nastran 2022.3 and 2022.4
  • DDB: Bug fix for unsymmetric B2PP calculations for fluid
  • DDB: Correction of the warning message issued in SOL 103 in case the method in EIGRL for normalizing eigenvectors specified with option MAX.
  • EXE: minor enhancements

 

CDH/FastFRS - Enhancements version 2.2.r188 compared to 2.2.r179:

  • DDB: Support of FastFRS usage in SOL 111 for fluid-only models with CAABSF absorber elements for NX/SC Nastran.
  • DDB: Bug fix for handling the fluid damping defined in MAT10 for NX/SC- Nastran.
  • EXE: Enable capability to support fluid-only computations that contain acoustic absorber elements (CAABSF/PAABSF).
  • EXE: On AMD EPYC machines running SUSE Linux, FastFRS failed with the system message “error while loading shared libraries: libirc.so: cannot open shared object file: No such file or directory”. This issue has been addressed by modifying the script that invokes the FastFRS executable, so that it does not reset LD_LIBRARY_PATH. If FastFRS runs on your system, you will not benefit from this modification, but if FastFRS fails in this manner, this fix should address the problem.
