There are four options for the POSITION parameter in the *EL FILE keyword in Abaqus. They are CENTROIDAL, AVERAGED AT NODES, INTEGRATION POINTS (default), and NODES.  However, in HyperMesh there are only two ways results can be presented: (a) unique value at the center of each element and (b) unique value at each node.  Therefore, Hmabaqus must manipulate results from the .fil file to some extent to fit the HyperMesh architecture as follows:

Hmabaqus reads these values directly and assigns them to the center of each element.  An assign plot reflects exactly what is given in the .fil file.  A contour plot contributes the same value to each of the element's nodes and for each node, values coming in from all adjacent elements are averaged to create the smooth contour image.

Hmabaqus reads these values directly and assigns them to each node.  A contour plot shows the exact values that were read from the .fil file at nodes.  For boundaries between components with material or thickness difference, there may be multiple values for a node in the .fil file. In this case, HyperMesh considers the last value for each node.  As a result, you may see a blending of color at nodes along these boundaries.  An assign plot averages the result coming from nodes of an element and assigns them to the centroid of the element.

This is the default option in Abaqus. Hmabaqus averages the values from each integration point to the centroid of an element.  For example, for an element with four integration points, Hmabaqus reads the values at each integration point, adds them, and then divides them by 4.  This usually gives an answer very close to POSITION = CENTROIDAL.  An assign plot reflects these averaged values at elements.  A contour plot contributes the same value to each of the element's nodes and for each node, values coming in from all adjacent elements are averaged to create the smooth contour image.

Hmabaqus does not currently support this option.
