3. Operands

3.1. Keyword MODELE_GENE

♦ MODELE_GENE

Name of the generalized model whose quality you want to check. The calculations carried out are detailed in the documentation [U2.06.04].

3.2. Keyword RESU_GENE

♦ RESU_GENE

Name of the generalized result on the basis of which the quality of the generalized model is checked, and which then allows enrichments to be calculated.

3.3. Keyword SHIFT

◊ SHIFT

Value of the frequency shift allowing to calculate the enrichment terms for the macro elements whose stiffness matrix would be singular once the conditions at the limits of the interfaces are freed.

This is for example the case in test SDLS122A, where we consider square macro elements, embedded on the edge associated with the interface, and simply pressed on the 2 other free corners. By freeing the embedment from the interface edge, the structure becomes articulated, and therefore has rigid body modes. In the absence of \(\mathit{SHIFT}>0\), the matrix is singular and the calculation cannot proceed correctly.

3.4. Keyword UNITE

◊ UNITE

Specify the unit of the file in which the results of the interface job calculations will be printed. By default, the results are printed in unit 8.

3.5. Keyword VERIF

◊ VERIF

Keyword factor inherited from the definition of the generalized model, in order to verify its consistency. It is determined whether the link is compatible or not. The nodes of the two interfaces do not in principle have to be ordered in such a way that they are combined two by two. If the interface nodes are not facing each other in pairs, the code detects this state and reorders the nodes so as to put them back facing each other.

3.5.1. Operand STOP_ERREUR

Allows you to check the consistency of the generalized model or not.

3.5.2. Operand PRECISION/CRITERE

Indicates the precision threshold beyond which the links are incompatible. This is the distance (relative or absolute according to CRITERE) clear of which the link nodes are considered too far apart to be effectively connected.
