Translations:FEM EquationElasticity/15/en

The elasticity equation provides these special settings:
 * : If the principal angles should be calculated.
 * : If all stresses should be calculated.
 * : If strains will be calculated. This will also calculate the stresses, even if or  is false.
 * : If stresses should be calculated. Compared to the Tresca yield criterion and the principal stress will not be calculated.
 * : See the Elmer manual for more info.
 * : If mesh can be deformed. This is by default true and must be set to false for eigenfrequency analyses.
 * : If displacements or forces are set. thereby is automatically used.
 * : Considers the geometric stiffness of the body.
 * : Computation of incompressible material in connection with viscoelastic Maxwell material and a custom.
 * : Compute the viscoelastic material model.
 * : Uses model lumping.
 * : File to save the results from the model lumping.
 * : If true becomes a stability analysis (buckling analysis). Otherwise a modal analysis is performed.
 * : See the Elmer manual for more info.
 * : The variable for the elasticity equation. Only change this if is set to true in accordance to the Elmer manual.
