![]() Running Comsol in Different Parallel ModeĪssuming other things are the same as in Example 1, we will show additional examples running in different parallel modes by changing the number of cores and the Comsol command line parameters.Įxample 2a (Terra): Solving a model in shared memory mode using 14 cores on one Terra cluster node. Save the above example to a file and run "sbatch file" to submit this job. #SBATCH -output=comsol.%j #Send stdout/err to "comsol."Ĭomsol -np 28 batch -inputfile in.mph -outputfile out.mph #SBATCH -mem=56G #Request 56 GB of memory per node #SBATCH -ntasks-per-node=28 #Request 28 tasks/cores per node #SBATCH -time=01:30:00 #Set the wall clock limit to 1hr and 30min #SBATCH -job-name=comsol #Set the job name to "Comsol" You need to pick the version you need to access.Įxample 1a (Terra): Solving a model in shared memory mode using 28 cores on one Terra cluster node. Ask for permission to use the license server maintained by the school of engineering.Purchase your own license (If you choose this route, you can either ask us to host the license server or you can host the server by yourself.).You can choose one of the following to get access: This is the same as OpenMP where the parallelism is limited by total number of CPU cores available on one compute node in a cluster.Ĭomsol is restricted software that is only limited to users and groups who have a license. By default, a Comsol solver runs in shared memory mode. This tutorial illustrates how to create Comsol LSF batch scripts on Ada.Īll solvers in Comsol can run in parallel in one of three parallel modes: shared memory mode, distributed mode, or hybrid mode. A job script must be created to run the model in batch so that you can control wall time, memory, and other cluster resources for your simulation. Once a model is built in Comsol GUI, the next step is to compute the model for a solution, which is often time-consuming. An API for Java and LiveLink for MATLAB may be used to control the software externally, and the same API is also used via the Method Editor. ![]() ![]() COMSOL provides an IDE and unified workflow for electrical, mechanical, fluid, and chemical applications. It allows conventional physics-based user interfaces and coupled systems of partial differential equations (PDEs). 4 Running Comsol in Different Parallel ModeĬOMSOL Multiphysics is a cross-platform finite element analysis, solver and multiphysics simulation software.
