Edge Distribution (FEM mode)
Click Home and then click the arrow next to Control. Click Edge Distribution. The Edge Distribution Control dialog box opens. Use this control to specify the number of nodes you want the mesh generator to create on one or more edges or curves in your model. This type of mesh control affects shells, bars, and solid meshes.
Specify the following information in the dialog box:
Name—Specify a name for the mesh control or use the default name.
References—Select one or more curves or edges or both. You can select the geometric entities before or after the dialog box opens. The References collector displays your selections.
To flip the direction of node distribution on the specified edge or curve, select the edge or curve again. The arrow on the specified edge displays the direction. Creo Simulate indicates that the distribution direction is flipped by adding the word reversed to the References field.
Properties—Specify the following properties of the dialog box:
Number of Nodes—Specify the minimum number of nodes you want distributed along the selected edge or curve. Creo Simulate may create additional nodes if the nearby geometry is complex.
First/Last Nodal Interval Ratio—Specify the ratio of the first interval on the edge or curve to the last interval on the edge or curve. For example, if you enter 3 as the ratio, the last interval will be 3 times the length of the first interval. The intermediate nodes will be spaced in graduating intervals proportionate to the ratio. If you enter a ratio of 1, all intervals will be equal.
Prevent Additional Nodes—Check this option if you want the number in the Number of Nodes text box to be a precise number. Creo Simulate will stop the mesh creation if it requires more nodes than the number you set. When the meshing fails, Creo Simulate highlights the edges requiring additional nodes.
The mesh generator only respects the Edge Distribution mesh control if you apply it to unmeshed components. If a component has a mesh, the mesh generator silently ignores the mesh control.
