Hi,
I would like to consider in my simulation, that the material properties (coefficient of friction, Young's modulus ...) of the particles are a function of temperature. There's heat conduction from wall to particles and the particles near the wall are heated up, so each particle has a different time dependent temperature and hence different values of material properties.
My idea is to calculate the material properties every time step for each particle using their current temperature.
Is there any possibility to realize that? If so, how can i do that?

Hi,
Hi,
currently the material properties are evaluated only once upon initialiazation, before a simulation run (run command) starts. So you could introduce a new property, which depends on the temperature (e.g. calculated by a fix) and include it into one or more force kernel(s)
Cheers

I want to heat up the base,
I want to heat up the base, where the particles lie and eventually the particles should get heated up. I am using " temperature " keyword at end of " mesh/surface" command which gave me segmentation fault and code crashes. So now I am adding temperature keyword after " wall/gran " command after "mesh" keyword , the script seems to be running but the immediate particles dont get heated up at all, In short, there is no difference after adding it. Please help, as to how to get the walls to have higher temperature than particles , and the heat to flow from walls to particles.
regards
Anand
