Hello Everyone, Thanks for your response. The problem is how to calculate the average strain and stress values using Area Average Method (for the geometry attached in previous mail)? I am using this formula *Avg Strain = (A1E1+A2E2.AnEn/A)* for the calculation. I have calculated the values o

Daniel, Side question: If I have to output gradients of a variable, the straightforward approach would be to evaluate the gradients over quadrature points and then average. This gives me an average value of my gradient per cell. Do you know how does data DataPostProcessor evaluates the value
