i had sage perform grad() on a scalar field and the calculation was really slow. grad() consists of several steps and apparently the derivative() is not the issue, but rather the simplification of the resulting terms thereafter. The process is described here: http://doc.sagemath.org/html/en/reference/manifolds/sage/manifolds/utilities.html#sage.manifolds.utilities.simplify_chain_real
How can i perhaps skip that step and use a faster alternative? My scalar field is a sum of some broken rational functions with a few sqrt() and squares in it. No trigonometric stuff. I guess that might make it possible to skip some steps in the simplification process. It is also possible to calculate all the grad()s on the individual broken rational functions seperatly and add them up afterwards. I don't think the terms will become simpler as a whole compared to individually. I would perfer if i could just plug in an other simplification algorithm for large terms, perhaps tweakable. Is that possible? what other options do i have? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
