Zoheir Khademian posted a new comment: Hey Robert, Sorry for my delays. I try to give your comments enough thoughts and do investigation before replying. I tried both released version [1] and development version [2] and still observed the instabilities meaning the particle temp goes above the max boundary temp while cell temp is still within the range. Regarding the diffusivity coefficient kA/L, in the MWE I uploaded last, I have reduced kA/L by reducing fluidk and fluidConductionAreaFactor to arbitrarily low values. I also tried your values (thermal.minimumFluidCondDist=rMean and thermal.fluidConductionAreaFactor=0.1) but still the particle temp is unstable. Finally I looked at the thermal.cpp and noticed that applyTempDeltaToSolids [3] adds pore temp differences to the solid temp for no apparent reason (particle temp is updated here [4]). I deactivated applyTempDeltaToSolids and recompiled the source. I ran the MWE and the results are stable now. Let me know if applyTempDeltaToSolids must not be deactivated or I am missing something here Thanks Zoheir [1] https://launchpad.net/yade/+download [2] https://gitlab.com/yade-dev/trunk [3] https://gitlab.com/yade- dev/trunk/-/blob/master/pkg/pfv/Thermal.cpp#L94 [4] https://gitlab.com/yade- dev/trunk/-/blob/master/pkg/pfv/Thermal.cpp#L605 -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
