Introduction to Effective Mesh


An effective mesh is a mesh that provide you maximum accuracy in less computational time. If the mesh is very fine, the result will be accurate but the time taken to obtain the result will be more. Therefore, it is very important to make proper balance between number of elements in a mesh and computational time taken for analysis. In Autodesk Simulation Mechanical, to make proper balance between number of elements in a mesh and computational time taken for analysis, you can create fine mesh only in the region of high stress and strains by adding the refinement points. Below figure shows the a model with mesh with refinement points added.

Variable Pressure

The variable pressure is applied by specifying different pressure magnitude along a direction of the selected surface at uniform intervals.

Hydrostatic Pressure

Hydrostatic pressure is a pressure that is exerted by a fluid at equilibrium. It varies linearly from the level of the fluid in the direction of increasing depth of the fluid. The magnitude of the hydrostatic pressure is directly proportional to the depth of the fluid and to the density of the fluid.


Remote Load

A remote load is a nodal load or boundary condition that is originated from a point that is located in the space, not on the model. In other words, the load that is originated from a point located in the space, transmitted to the model through line elements such as beam, truss, or similar line elements is called as remote load. You can apply a remote load like you apply a force on the model with the only difference that the location of the remote load origin can be anywhere in the space.
