Since pressure/shear interactions are boundary conditions interactions (LoadingInteraction), no materials must be associated to the element.
Therefore, the first step consist in defining an ElementProperties, as
prp = ElementProperties(typeEl) prp.put(param1, value1) prp.depend(param1, fct1, Lock1)) #optional ...
where
typeEl | desired element (for example Tm[2]Convection[2|3]DElement) |
param1 | name of the property associated to the element (for example CONV_COEF |
value1 | value of the corresponding property |
fct1 | function which characterizes the dependency of the property (optional: no fct if no dependency) |
Lock1 | Lock which defines the dependency variable of the property (compulsory if there is a dependency) |
Convection element in 2/3D, first or second order (thermal field of second order)
| Name | Description | Dependency |
|---|---|---|
STIFFMETHOD | Method used to compute the stiffness matrix\\= STIFF_ANALYTIC : analytic matrix (default)= STIFF_NUMERIC : numerical matrix | - |
CONV_COEF | Thermal convection | time |
TEMP_FLUIDE | Temperature of the fluid | time |
NPG | Number of integration points (default : tm : 2 / tm2 : 3) | - |
The interaction is defined as:
load = LoadingInteraction(no) load.push(gObject1) load.push(gObject2) ... load.addProperty(prp) interactionset.add(load)
where
no | number of the Interaction |
gObject1, gObject2 | mesh geometric entity where the boundary conditions are applied |
prp | Properties of boundary condition elements to generate |
