How to generate domains using Mertis ?

[36051121]

I want to try parallel FEAP. How to generate domains using Mertis ?  What is the command to cut the mode into several submodels for parallel FEAP. I find no command line in the ParaFEAP manual.
I have installed the Para FEAP and wrote the input file according to the ParaFEAP manual. But when I type  'feap -iIfile', it reads '
*ERROR* GRAPh command only available in parallel version
 *ERROR* OUTDomain command only available in parallel version''

You must run the parallel version of feap to do the graph partitioins.

You must run the parallel version of feap to do the graph partitioins.

I do not know the command for parallel FEAP, though I have installed parallel FEAP successfully. Is the command ´feap -iIfile´? But it does not work.
I have not found the command for parallel FEAP in the manual.
Many thanks.

The parallel executable is at $FEAPHOME8_4/parfeap/feap .
For the purposes of partitioning you execute it just like the serial version.

> $FEAPHOME8_4/parfeap/feap

The after setting the file names you can call the graph partitioner with GRAPh,node,4 (for example for a 4 domain partitioning) followed by OUTDomain,aij,1 (for example for AIJ output with boundary equations included).

I faced the same problem. You can try the following steps:

1. Go to the "parfeap" subdirectory. For example:

/FEAP-83-2011-new/ver83/parfeap

2. In the "parfeap" subdirectory, you must have the input file that you want to split. For example "Ipatch_4el" is the input file that you want to split.

3. Run the executable file "feap" using the following command:

mpirun -np nump feap 2 Ipatch_4el

4. Enter the name of your input file (Ipatch_4el) when asked.

5. After running, you will see the following 2 files:

    -Ipatch_4el_0001
    -Ipatch_4el_0002

So, I think these are the steps to split an input file into several input files. Let me know if this helped!
