jellespijker / pymech

Continuation for this project is stopped. Focus is now on the MechEng modules ( https://github.com/mecheng ) A Python module for mechanical engineers. Project which is mostly based on the books of Roloff / Matek (Machineonderdelen), Hibbeler (Statics, Mechanics and Dynamics), Kals (Industriele productie) and R. Mott (Applied Fluid Mechanics). Al calculations are unit/dimension save. Using IPython / Jupyter a report can be generated in LaTeX, html or PDF Currently implemented: * Force method calculation for a simple beam * Unit based calculations * Axle calculation * Material properties

Solver in system doens't converge #21

Open jellespijker opened 7 years ago

jellespijker commented 7 years ago

Solver is based upon Linear theory method. First iteration looks correct then it starts oscillating. Check if it has something to do with the negative flow when to To-From assumption was incorrect.
