Thanks Sampad, I am looking for the error. Meanwhile, I just saw if the *length *of a beam is symbolic, then a lot of quantities have terms like *SingularityFunction(L, 0, n) *when they can be written simply. For example, support reactions for a simple beam problem: >>> b = Beam(L, E, I) >>> b.apply_load(R1, 0, -1) >>> b.apply_load(R2, L, -1) >>> b.apply_load(P, L/2, -1) >>> b.solve_for_reaction_loads(R1, R2) >>> pprint(b.reaction_loads) ⎧ 1 1 ⎫ ⎪ L 0 L ⎪ ⎪ -P⋅<─> P⋅<L> ⋅<─> 0⎪ ⎨ 2 2 L ⎬ ⎪R₁: ────────, R₂: ─────────── - P⋅<─> ⎪ ⎪ 1 1 2 ⎪ ⎩ <L> <L> ⎭
both *R1 *and* R2 *are simply *P/2* and the above thing makes it difficult to read. I think *SingularityFunction(L, 0, n) *can be a simple *Pow* with the same order, as for a beam *L *cant never be zero. Should I create a PR correcting this? What do you say Jason?
