  Hi Everyone,nI wanted to ask if anyone has knowledge on creating a custom constitutive equation in ANSYS, preferably through scripting if possible. My thesis seeks to use a machine learning algorithm (ML) to predict atomic level dislocations, and we would like to use a commercial software rather than creating FEA from scratch. The objective would be to simply replace the existing constitutive equation with our ML. Any thoughts are most welcomed.nBest,nGregoryn
