Thanks a lot Wenqing and Nori!
Removing the $COMPRESSIBILITY keyword from the .MFP file made it work fine.

Best Regards,

Guillaume

maybe you should try without $COMPRESSIBILITY part in the MFP file. I
think the keyword is used only for gas phase.

Unfortunately I am using windows. I have just retried with all input files
but it is stuck again at the same step.

It’s weired. Just tested on my machines again. Even with the debug model
executable file, running to the start of time stepping took a couple of
seconds. If you use Linux, please run dos2unix to all input files.

Yes I used the files in your last email. WIthout the Fluid Properties file
the simulation goes through in few minutes. But ehn the .MFP file was
included it stuck at ‘MFPRead’ for nearly 30 minutes.

Did you use the files in my last email? I have tested them with the
master in https://github.com/ufz/ogs5, and the program ran without any
problem in reading files.

For the 3rd material group of an incompressible and viscous liquid, you
can use treated as hard solid with a relatively large Youngs’ modulus.

I have a problem there. the 3rd material group (material ID 2 in the mesh
file) (the sphere representing a magma chamber) is an incompressible and
viscous liquid. How should I define its properties in the solid properties
files?
The Fluid properties file contains the properties for this material
group.
I tried to run the simulation. It was reading the .MFP file for 30
minutes. I stopped the computation and deleted the . MFP file from the
folder. Now it is running properly. But I guess the results will not be good
until I properly define the material groups and properties.

Thanks in advance!

In Correction 3), I just copied a section of solid property from the
existing one for testing, and you have to change it according to the
definition of your example.

Four corrections:

  1. changed all files extensions to small letters (not important).
  2. removed one domain ddc file (sequential computation with DDC increase
    computation time)
  3. added one solid property. The original file has only two solid
    properties, however the mesh has three material domains.
  4. corrected subdomain initial condition input under keyword FUNCTION,
    which takes the form:
    a+bx+cy+dz
    where any of the term can be ommited, e.g. just d    z

Correction 3) avoid the the program crashing.

The corrected files are in the the attached zip file. Before extracting
the files, please rename the zip file extension zipp to zip.

Thanks a lot Christoph and Wenqing,

I will wait for the feedback.
