The latest available COMSOL version on the clusters is 5.2. There are two variants of the release:
There are two types of license:
***Non commercial** or so called **EDU variant**, which can be used for research and educational purposes.
***Commercial** or so called **COM variant**, which can used also for commercial activities. **COM variant** has only subset of features compared to the **EDU variant** available. More about licensing [here][1].
To load the default `COMSOL` module ([**not** recommended][4]), use:
```console
$ml COMSOL
```
By default, the **EDU variant** will be loaded. If you needs other version or variant, load the particular version. To obtain the list of available versions, use:

## LiveLink for MATLAB
COMSOL is a software package for the numerical solution of partial differential equations. LiveLink for MATLAB allows connection to the COMSOL API (Application Programming Interface) with the benefits of the programming language and computing environment of the MATLAB.
COMSOL is a software package for the numerical solution of partial differential equations. LiveLink for MATLAB allows connection to the COMSOL API (Application Programming Interface) with the benefits of the programming language and computing environment of MATLAB.
LiveLink for MATLAB is available in both **EDU** and **COM****variant** of the COMSOL release. On the clusters there is 1 commercial (**COM**) and 5 educational (**EDU**) licenses of LiveLink for MATLAB (see the [ISV Licenses][3]). The following example shows how to start COMSOL model from MATLAB via LiveLink in the interactive mode.
This example shows how to run LiveLink for MATLAB with the following configuration: 3 nodes and 128 cores per node. A working directory has to be created before submitting (comsol_matlab.pbs) job script into the queue. The input file (test_job.m) has to be in the working directory or a full path to the input file has to be specified. The Matlab command option (`-r ”mphstart”`) created a connection with a COMSOL server using the default port number.
