Errors

[iviejo]

The code has serveral errors:

• It is only valid for grid points =5
• Implicit solver not take into account te
• ...

Thanks for pointing out the errors, will check and update.
Could you specify the line number in code?

To be valid for different discretization the line:
df = pd.DataFrame(columns=["Node: 1", "Node: 2",
"Node: 3", "Node: 4", "Node: 5"])

Should be:
header=[]
for i in range(n):
header.append("Node: %i" %i)
df = pd.DataFrame(columns=header)

For the other error, I have not clear because I don't know the details of TDMA implementation. Tha fact for the implicit method you could solve directly a linear solver problem Ax=b

Fixed number of nodes issue. If any other errors are found feel free to open a new issue.
