** WARNING 702352 ** Element %7d and %7d are overlapping or too close. The analysis may not be able to resolve these problem elements during analysis. It is recommended that you improve the mesh in the region of these elements.
During the boundary element integration of the Cool analysis, two elements were found to be in too close proximity to one another. If the distance between the centroids of two elements is less than 10 percent of the average edge length of either triangle, then the warning is triggered. This warning usually occurs when two triangular elements of very bad aspect ratios are adjacent to each other. Another common cause is between two adjacent triangular elements of good aspect ratio that form a fold in the part and consequently have a very small included angle between the two elements. With Dual Domain meshes, this warning could arise when the part thickness is very thin and the opposing triangles are too large. This warning may also arise if a cooling circuit element intersects a triangular element.
Locate the elements specified in the message using and check the aspect ratios of those elements. If the aspect ratios are very high, then the elements require modification. If the two elements form a fold in the part, then the angle between the two elements needs to be increased by modifying the model. If the problem relates to two opposing Dual Domain elements, then the part has to be re-meshed with a smaller edge length. If the problem is due to a beam element intersecting another element, the modeling error needs to be corrected.
