Hi,
I’d like to calculate the large deformation strain tensor in a 3D deforming model. The formula is as follows:
where x’ is the reference/initial coordinate, and the deformed coordinate x = x’ + u. I tried with Compute Derivates
and Gradients
filter, however, I think these 2 filters can only take derivates of the deformed coordinates x. Is there a way to take derivates of x’?
I used the Calculator
filter to compute x’ = x - u, but I cannot find a function in both Calculator
and Python Calculator
with can let me compute du/dx’. Anyone has any ideas?
Thanks in advance,
Gening
