Advantages of Combining Trimmed Surfaces

With TrueGrid® you easily combine many trimmed surfaces into one surface by simply identifying them.

TrueGrid® imports models built from hundreds of complex trimmed surfaces.

TrueGrid® displays a faithful reproduction of the model.

Child Proof Cap with Many Trimmed Surfaces

The helical thread in this cap is considered difficult to model with hex elements. But when a block mesh is projected to the combined surfaces, the problem is easily solved.

Filleted areas are commonly decomposed as shown below. Just the single tab shown here is composed of 16 surfaces. It is critical to be able to combine such surfaces into one to avoid spending disproportionate amounts of time on small features.

The mesh is finished by interactively adding elements, and smoothing various faces using one of the TrueGrid® elliptic solvers.
