-For a given boundary, this solver computes the nodal normal ​stress equivalent to a given nodal normal ​force. This can be used also to infer the flux from the knowledge ​of a debit (should work also to infer a tangential ​force from the knowledge ​of a tangential force)+For a given boundary, this solver computes the nodal stress equivalent to a given nodal force. Force here means the result of a variable, named stress, which is of the same units than the force but per unit-area in 3D or unit-length in 2D. This can be used also to infer the flux from the value of a debit or to infer a tangential ​stress ​from the value of a tangential force. ​
