How can I use multiple cores, when running Mechanical APDL out of Matlap

  Hi,
  
  I have a the problem that, when I use Matlap R2019a to run Mechanical APDL it only uses 2 cores.
  
  I already changed the core count to 8, how it is desribed in the link below. The problem is it didn´t change the number of cores Ansys uses when using matlap to run it.
  
  Here is the link I´m talking about: https://forum.ansys.com/forums/topic/configuring-from-2-core-to-4-core-processor-for-ansys-18-2/
  
  I hope somebody has a solution. Thanks

  What is the command line you are using to run the ansys solver from matlab?
  
  Is it something like this?
```
/home/ANSYS Inc/v194/ansys/bin/Linux64/ansys194 -b -i input.dat -o solve.out
```
  All you need to do is add the flag -np 8 and it will run on 8 cores.
