Use the Measure () node to compute the difference in displacement, velocity, acceleration, or any other quantity between two selected points. Result variables for distance, relative displacement, velocity, acceleration, or any other input quantities are available under Result Templates.

The Global coordinate system is selected by default. The Coordinate system list contains all applicable coordinate systems in the component. The coordinate system is used for interpreting directions of orthotropic and anisotropic material data and when stresses or strains are presented in a local system. The coordinate system must have orthonormal coordinate axes, and be defined in the material frame. Many of the possible subnodes inherit the coordinate system settings.

The relative displacement, velocity, and acceleration vectors are given in the Global coordinate system and other possible system selected in the Coordinate system list.

Select the reference and evaluation points from either Point or Coordinates.

You can only select one reference point and one evaluation point, so that variables between these two points are measured. If you want to measure variables between different points, you can sequentially change the point selections, or add several Measure nodes with different reference and evaluation points.

Use the Add button () to add a row to the table, the Delete button () to delete a row in the table, or the Clear Table button () to clear the whole table.

Use the Load from file button () and the Save to file button () to load and store data in a text file with three space-separated columns (from left to right): the variable name, the expression, and its description.
