Dear all
With respect. I using icoFsiElastciNonLinSolidFoam to simulate Hron Turek benchmark. the default tutorial is not consider. I use other test with fluid density 1000, v=1e-3 and solid density 10000, E=5e5, v=0.4. My problem is that after 4.48 second, model has error, after changing fvscheme and delete some results from [4 4.48], then run again in time 4s, the solver need grad(Du_0) and grad(Usolid). I choice Guass linear for them. the simulation will start from last time (4s), but pointhistory give different number. For example I uses HTML Code:
pointHistory { type pointHistory; functionObjectLibs ("libpointHistory.so"); region solid; refHistoryPoint (0.6 0.2 0.025334); } In second time=4second ( -0.30060291207 0.0094709455648 0) sometimes, I need to stop running and start again, but the problem is same. my question is: why results different? why solver need Du_0 and Usolid? how run solver again and continue from previous time? Thanks |
