Hello all, I have come across what may be an error in genbox. It concerns reading in data. If instead of 8 elements, 7 are used or if the trailing zeros are removed, all is fine. It almost seems as if genbox has a limitation on the length of the lines defining the element edges. Cheers, Frank Reading 32 = 8 4 4 elements for box 1.

Hello all, Genbox has an issue in that the number of characters in a line for its input file was <= 80. This makes it impossible to have a large number of elements in one direction if one is specifying the element locations. A solution is to extend the line length to 9999999.

Thanks for bringing this up. That's a typical situation. We know Nek and the Tools are not straightforward to use and there are many undocumented tricks and options. It simply takes some time to become familiar with it. But I guess that's true for all software. Sorry for all the trouble. Stefan On May 3, 2010, at 10:33 PM, [email protected] wrote:
