ANSYS中單機多核執行lsdyna或者autodyn並不需要單獨安裝Intel或MS的並行平臺。自2020版本起,autodyn並行不在支援IBM。網上搜索發現還沒有人成功使用Intel MPI平行計算。 下面的描述來自官網問答。
before continuing check MPI is installed or not Method 1: keep ready with your model, allocation the subdomin to particular cores, save and close the AutoDyn open cmd enter cd C:\Program Files\ANSYS Inc\v193\aisol\AUTODYN\winx64 ( go to this directory, version and installation disk may varies ) enter AUTODYNWRAPPER.exe -noinput -machines "xxxxx:16" (xxxxx = your system name, you can find it in 'My computer> system properties' or Control Panel\System and Security\System, 16= n.o of cores - give same as n.o of task you allocated in the model) above commands will launch AutoDyn go to file>open the xxx_0.ad file now click run if you edit some thing after launching AutoDyn from cmd or stopped in between you have to repeat the same steps from beginning you can check the performance of each core in View>Performance Profile, before that you have to create a empty text file in working directory where xx_0.ad file is available, name it as profile.cfg, before executing RUN open the Performance profile where you can find the performance of slave processor with respect to 1, make the all slave processor close to 1 for optimum utilization of hardware. Method 2 - you can find more about in help section 3.1.2. Running Autodyn with Intel MPI create applfile and autodyn_mpi.bat as per 3.1.2 save those file in winx64 same path as above enter cd C:\Program Files\ANSYS Inc\v193\aisol\AUTODYN\winx64 enter autodyn_mpi.bat above commands will launch AutoDyn remaining and all same as above method Create a file called applfile, and in this file enter the following text, making the relevant changes for your parallel model, machine names, and installation path, should the installation not be in the default location: -localroot -env ANSYS_EXD_MPI_TYPE intelmpi -host [machinenameA] -np 1 –wdir "C:\Program Files\ANSYS Inc\v170\aisol\AUTODYN\winx64” autodyn.exe -host [machinenameB] -env ANSYS_EXD_MPI_TYPE intelmpi -np [number of slaves] "C:\Program Files\ANSYS Inc\v170\aisol\AUTODYN\winx64\adslave.exe" create a blank file called autodyn_mpi.bat. In this file enter: set I_MPI_ROOT=%AWP_ROOT170%\commonfiles\MPI\Intel\4.1.3\winx64 "%I_MPI_ROOT%\bin\mpiexec.exe" -configfile applfile Once the batch file is executed, Autodyn starts, along with the number of slaves specified in applfile. You can now create your model or load an existing one and proceed with your analysis. ···
