Hi

I am doing a 3D simulation of solder joints that are being submitted to a thermal cycling. I have implemented a PDE for the creep strain (d?/dt). I am now looking to determine the average strain (?) over each subdomain. However, I am not quite sure about my method

I am using the subdomain integration on the pos processing options then I am integrating (order 1) the d?/dt over time. So my doubt is:

Is the integration of the d?/dt the average strain (?) over of the integrated subdomain ?

Which integration order I should use?


Anyone knows
