Please check each page shown in the left for the details of each SW. This page describes common steps of running main applications.

• Or check: https://studentcommunity.ansys.com/thread/runtime-errors-on-centos-7-system/)
  • export LD_LIBRARY_PATH+=/ansys_inc/v192/Framework/bin/Linux64/Mesa
  • export LIBGL_ALWAYS_INDIRECT=1
  • export LIBGL_ALWAYS_SOFTWARE=1 -License server/port is supplied from system variable
  • In Windows, it is hard-coded in c:\Program Files\ANSYSInc\Shared Files\Licensing\ansyslmd.ini

• copy /ansys_inc/v192/ansys/data/models/CrankSlot_Flexible.inp
• Command: ansys192 -np 2 -i CrankSlot_Flexible.inp > log.out
  • file.rst, file.db will be produced
• Command: launcher -> Select PrepPost from License -> Click run
  • In the menu, General Postproc -> Results Viewer -> Select file.rst

• fluent 3d -g # run fluent 3d without grahics
  • file/read-case-data catalytic_converter.cas.gz # read input
  • it 10 # do 10 iterations
  • wcd "aaa.cas" # save as aaa.cas
  • exit # exit fluent terminal
• fluent 3d # open as GUI
  • File-> Read -> Case & Datat -> select aaa.cas
  • Click Postprocessing tab -> Graphics zone -> Contours -> Select velocity or Pressure
  • If OpenGL graphics crashes, use software rending as fluent 3d -driver x11

• Edit the line 34 of ansys_inc/v193/icemcfd/linux64_amd/lib/ai_env/techTK/layout.tcl
• From set SmallScreen 0 to set SmallScreen 1

• Steps
  • copy /ansoft/AnsysEM19.1/Linux64/Examples/HFSS/RF\ Microwave/coaxial_resonator.aedt
  • ansysedt -distributed -machinelist numcores=2 -auto -monitor -ng -batchsolve -batchoptions "HFSS/HPCLicenseType=pool tempdirectory=/tmp" coaxial_resonator.aedt
  • ansysedt # GUI, open coaxial_resondator and Check Filed Overlays

• abaqus fetch job=lap*.inp # extracting a sample input
• abaqus j=lap_joint inter cpus=2 (or 4, 8, 16, 32)
  • Using htop, check if cpus are used as many as requested
  • Took 86 sec in 2 CPUs of Broadwell
• abaqus cae
  • Open lap_joint.odb and visualize

• comsol batch -nn 1 -np 1 -inputfile heat_exchanger_iso.mph -outputfile aaa.mph
  • Batch command using 1 cpu
• comsol
  • GUI. Open aaa.mph and check Results -> Temperature
• comsol -nn 1 -np 4
  • Opens GUI with 4 cpu for multi-prcoessing
• comsol -nn 1 -np 4 -3drend sw
  • Opens GUI with 4 cpus parallel computing and SW rendering for visualization

• Run bench in the MATLAB comand interface
• This will test CPU speed and 3d graphics

• Compatibility with JAVA
  • Try JDK from OS or JAVA engine from SUN
• Graphics issue
  • When HW rendering fails, run matlab as matlab -softwareopengl with SW rendering

• tec360

• tec360 -mesa
• Note that SW rendering is much slower than HW rendering
