Working of User Defined Constitutive Model

[jwang]

Since the model ‘example’ was a CPP built model, you have to use z_prop() fish function to extract the properties from the zones. Please see the following post for more details:

Use z_model(),z_prop() and z_group(). to access model and properties

1.To access CPP (CPP built-in and CPPUDM) models and their properties: Use: z_model() to return or modify model name. e.g. if z_model(i,j)=‘finn’ z_prop() to access property name. e.g. _fric=z_prop(i,j,‘friction’) To access other models and their properties: Use: model() to get the constitutive model number. e.g. if model(i,j)= 3 ;Mohr-Coulomb model A list of models on page 2-43 of Fish Reference manual. To access model properties, use the property name directly. e.g. _coh= cohesion(i,…
