Weyl Tensor calculations using Symbolic module

from sympy import cos, sin, sinh

from einsteinpy.symbolic import MetricTensor, WeylTensor



sympy.init_printing()

Defining the Anti-de Sitter spacetime Metric

syms = sympy.symbols("t chi theta phi")

t, ch, th, ph = syms

m = sympy.diag(-1, cos(t) ** 2, cos(t) ** 2 * sinh(ch) ** 2, cos(t) ** 2 * sinh(ch) ** 2 * sin(th) ** 2).tolist()

metric = MetricTensor(m, syms)

Calculating the Weyl Tensor (with all indices covariant)

weyl = WeylTensor.from_metric(metric)
