In many cases, CAD geometry may be imported in an undesired location/orientation, and the geometry needs to be moved to a new location/orientation for your StressCheck analysis.

What Are the Requirements for Using Triangle and/or Quadrilateral Elements in StressCheck?

In StressCheck, Triangle (3-sided) elements and Quadrilateral (4-sided) elements are available for meshing geometric surfaces and curves for subsequent engineering simulations. The following are the requirements (and limitations) for using Triangle and/or Quadrilateral elements in Planar, Extrude, Axisymmetric and 3D analyses.

In certain situations, an error message may appear when attempting to perform a geometric operation (e.g. Boolean-Union) or when attempting to delete an existing geometric object/body. The error message may appear similar to the following:

What Ranges Are Applicable for Offset, P1 and P2 (Min/Max) Inputs?

Date: October 7, 2019

Categories: Model Inputs, Results Plotting & Extractions

In general the range when entering Offset, P1 (Min/Max) and P2 (Min/Max) inputs for object generation, or object boundary extractions in the Points tab, is typically normalized to [0,1]. However for some geometries, such as spheres, cylinders and cones, the P1 (Min/Max) and/or P2 (Min/Max) inputs may be conveniently entered in degrees.

What’s the Difference Between DeLast and Undo?

Categories: Model Inputs

Both DeLast and Undo commands remove previously successful operations from StressCheck sessions. However, there are important differences as they relate to the model.

What Intrinsic Functions and Mathematical Expressions Are Supported in StressCheck?

Date: October 9, 2019

Categories: Model Inputs, Results Plotting & Extractions

StressCheck supports the use of certain intrinsic functions and mathematical expressions (FORTRAN or Mathematica conventions) when defining parameters and/or formulae. For example, "sin(x)" for sine(x), where "x" is a user input in radians.

How Do I Round A Parameter To Nearest Integer Value?

Date: December 19, 2017
