Cannot find msvcr90d.dll

If you see this message coming up, find the file PythonDir\Lib\site-packages\numpy\distutils\ and modify the line msvcr_dbg_success = build_msvcr_library(debug=True) to read msvcr_dbg_success = False (you can comment out the existing line and add the new line immediately after).

Problems with numerical integration

If the beginning of a run takes a long time, the reason might be the automatic determination of a suitable numerical integration algorithm. This can in particular happen for complicated equations where sympy’s solvers take a long time trying to solve the equations symbolically (typically failing in the end). We try to improve this situation (see #351) but until then, chose a numerical integration algorithm explicitly (Numerical integration).
