dx for LTEA, SMS


Recommended Posts

hi Guys,

Default value for dx is set to 1000 for LTEA analysis, and if we make it smaller, let say 500, the range of mesh size also getting smaller by experience.

However, I don't exactly understand how it works.

Simple description of dx and/or any reference would be very welcome, thanks.

The dx value for LTEA does not control the mesh size. The mesh size comes from a distribution of nodes based on the LTEA ananlysis and result in a specified target number of nodes.

The dx value is a base grid size utilized by the LTEA calculations. Basically, it is the limits the how quickly the distribution can change in more than a linear fashion.
