Hi @zhishuaizhang. It looks like a linear solver problem to me. Maybe a quick check is to try the direct solver if your problem is not too large.
Hi @frankfeifan Thank you very much for your suggestion! I changed the linear solver in Hydrofracture
to a direct solver as shown below but was still not able to have the modeling finish running.
<LinearSolverParameters
solverType="direct"
preconditionerType="none"/>
anyone is looking into that?
Two changes in the input seems to help to at least finish the case:
<LinearSolverParameters
solverType="gmres"
preconditionerType="mgr"/>
<TwoPointFluxApproximation
name="singlePhaseTPFA"
meanPermCoefficient="0.0"/>
I'm trying to run the hydraulic fracturing example in the basic example of the tutorial: https://geosx-geosx.readthedocs-hosted.com/en/latest/docs/sphinx/basicExamples/hydraulicFracturing/Example.html
It turns out that GEOS stops converging after about ~6 minutes out of a total of 20 minutes of modeling. I didn't change any parameters in the input files.
I tested with different nonlinear solver parameters but was not able to solve the problem... I am attaching the log file from running the original example for reference.
Thanks a lot! heterogeneousInSitu_benchmark_6_2_3.log
