**impose_element_dof_reaction

Description

This command imposes the conjugate reaction to an element degree of freedom.

Syntax

The syntax takes an element set name, the name of the degree of freedom for which reaction will be fixed, a scale value, and a table name (required for non-zero value).

**impose_element_dof_reaction \(~\,~\,\) elset  dof  value  table

Example

The following example apples mixed mode loading to an RVE element with the impose_element_dof_reaction conditions directly imposing the stress. This demonstrates the use of an element number for the element set. Note that E22 is given to fix \(\sigma_{22}\). This is because the reaction is specified by the degree of freedom name, which is the strain in RVE elements.

**impose_element_dof_reaction_rate

This command imposes the conjugate reaction to an element degree of freedom on a rate basis. Its syntax is similar to **impose_element_dof_reaction.
