Description
Describe the question
I want to add element weight information when initially dividing the domain using METIS, but after re-division the calculation result is correct for solids and incorrect for fluid-solid coupling.
My method is as follows:
- divide all elements into Rank0 to get the cell's constitutive information and the weight information
- re-divide domain with METIS
Platform
- GEOSX version 0.2.0 ( sha1: 42d058a41)
- Machine [Ubuntu18]
- Compiler: [gcc 8.3.0]

Research direction
Start by reproducing the two-stage METIS partitioning described for GEOSX 0.2.0 at commit 42d058a41 on Ubuntu 18 with GCC 8.3. Compare the solid result with the fluid-solid coupling result after re-division. Done means identifying the cause of the incorrect coupling calculation and documenting a verified correction or limitation.
