Import ANSYS File: Body Loads

Description

ANSYS uses BF to apply nodal body loads to nodes. Valid load labels include TEMP. Strand7 assigns the nodal body loads as initial node temperature attributes.

ANSYS uses BFCUM to specify the accumulation method for nodal body load values in accordance with load label TEMP. BFCUM applies to loads specified by the BF command. Strand7 references the accumulation method when nodal body loads are applied to plate or brick elements which have been previously assigned a value.

ANSYS uses BFSCALE to scale previously defined nodal body load values in accordance with load label TEMP and the node set defined by NSEL. Strand7 applies the scaling factor to the node temperature attribute assigned to nodes defined by the current node set.

ANSYS uses BFE to apply element body loads to elements. Valid load labels include HGEN. Strand7 assigns the element body loads as plate or brick heat source attributes.

ANSYS uses BFECUM to specify the accumulation method for element body load values in accordance with load label HGEN. BFECUM applies to loads specified by the BFE command. Strand7 references the accumulation method when element body loads are applied to plate or brick elements which have been previously assigned a value.

ANSYS uses BFESCAL to scale previously defined element body load values in accordance with load label HGEN and the element set defined by ESEL. Strand7 applies the scaling factor to the plate and brick heat source attribute assigned to elements defined by the current element set.

ANSYS uses BFUNIF to apply a uniform body load to all nodes. Valid load labels include TEMP. Strand7 assigns the uniform body load as initial node temperature attributes.

ANSYS uses TUNIF to apply a uniform temperature to all nodes. Strand7 assigns the uniform temperature as initial node temperature attributes

Time and Temperature Varying Values

Strand7 allows time and temperature varying heat source values, or time varying temperature values, to be assigned with a tabular boundary condition of array type TABLE and primary variables TIME or TEMP. Time varying or temperature varying plate and brick heat source values are assigned with a Factor vs Time or Factor vs Temperature table. Time varying initial node temperatures are assigned Factor vs Time tables. As specified by ANSYS, Strand7 assumes the hierarchical command order of D, BF and BFUNIF/TUNIF for assignment of node temperature attributes.
