gradient calculation

[lb_yuan]

Hello,

I have a self-defined field called 'prev_temperature'. When I calculate its gradient with field_gradient_scalar, it just crushes. The following is the error message.

/home/bliu/Desktop/Code_Saturne/code_saturne-5.0.8/src/base/cs_field.c:3351: Fatal error.

Field "prev_temperature" with type flag 144
has no value associated with key 37 ("var_cal_opt").

Hello,

Yes, this is a known limitation of gradients for "property" and not "resolved" fields, which do not have boundary condition settings. Well try to improve this, but for now:
