Setting the Reference Values

To view the global reference values required for the selected meshing models, open the Continua>Mesh 1>Reference Values node. The following mesh inputs will be listed:

For this example, absolute size specification is used for the prism layer thickness and surface size values. Although the model dimensions are in meters (automatically set during the import process of the Parasolid Transmit file), you can use any units to specify the inputs for the meshers.

The # Points in a gap value for Surface Proximity is increased so that an increased surface triangulation density will be obtained in the vicinity of the pipes and inner cylinder surface, which in turn will result in a higher concentration of volume cells.

To set the reference value parameters, click on the relevant node and enter the above values in the Properties window. For example, to set the prism layer thickness, do the following:

The absolute size specification can now be set.
