Apply a new attribute data or substitute an existing attribute data for an element that changes with the construction stage. It can be used in construction stage-using analysis (Static/Slope analysis, Seepage/Consolidation analysis).

General

Select the target element and specify the element property subject to change.  

Construction Stage

If the construction stage is specified, change the element property collectively.

For example, apply a stage by stage change in the material property of shotcrete, from ductile to hardening, of a 3D model. If the mesh set is already specified by shotcrete 001 ~ shotcrete 010, the boundary conditions for element property change need to be specified separately for each element when using Change property > General. However, for Change property > Construction stage, selecting shotcrete 001 ~ shotcrete 010 can create 10 boundary condition sets with just one click.

The name of the boundary condition set can be specified by [Replace substring of selected Mesh], [Fixed Prefix] and [Add Prefix] to collectively change the name of the created mesh sets. If nothing is input, the boundary condition set is created with the same name as the mesh set.

[Replace substring of selected Mesh] : Create a boundary condition set by using a different postfix on the selected mesh set name.

[Fixed Prefix] : Create a boundary condition set by adding a different prefix, instead of using the selected mesh set name.

[Add Prefix] : Create a boundary condition set by adding a prefix to the selected mesh set name.

Boundary set

Register the set constraint conditions on the desired boundary set. The user can specify the name of the boundary set.

[Change Property] can be used when the element properties change with the construction stage. If the ground has a property A in Stage 1 and that property changes to B in Stage 2, which then changes to property C in Stage 3, the following two boundary conditions are created.

Boundary condition 1 : A -> B

Boundary condition 2 : A -> C

Using Define construction stage, activate Boundary condition 1 in Stage 2 and for Stage 3, activate Boundary condition 2 and deactivate Boundary condition 1.

As a result, an element property that changes by A->B->C can be defined.
