Sub-modelling techniques on fixed and floating structures

In many cases global analysis provides insufficient stress information in local areas. The sub-modelling technique of the Submod software module allows taking a closer look at details without refining the entire model. In fatigue analysis of floating vessels and complex jacket joints this approach is normally a requirement to obtain reliable results. Submod takes global model results and a local model as input to compute the boundary loads (prescribed displacements) along the edges of the local refined model.

What you get with Submod software

• Provides detailed stress information in highly stressed areas based on the results from global analysis
• Quick and easy refined analyses
