  Hi there, nI need to subtract my kayak model (surface, shell) from a body (envelope) to do CFD analysis, but I can't do it in Design Modeler. Could you please help me? Thanks in advance.n

  Close the opening in the Kayak surface model and you can sew the surfaces together to form a solid, then you can subtract it from the fluid domain.n

  nIn SpaceClaim, select the edges of the opening, then click the Fill button. Do you have access to SpaceClaim?n

  In DesignModeler, use Concept, Surfaces from Edges. Then Create, Body Operation, Type = Sew, Create Solids? = Yes.n

  Yes, you have to create the surface from Cocept ---> Create a surface from edges (or sketches) and then substract.n
