Dear openCARP Community,

I'm trying to run the 2D example of the tutorial: Tuning velocities and anisotropy ratios

with the command:

`./run.py --velocity 0.6 --converge 1`

However, the algorithm does not converge and yields the following output:

No capture or decremental conduction, proximal quarter of tissue not fully activated

Assuming slow conduction velocity of 0.05 m/s in next iteration

Conduction velocity: 0.0500 m/s [gi=0.1740, ge=0.6250, gm=0.1361]

No capture or decremental conduction, proximal quarter of tissue not fully activated

Assuming slow conduction velocity of 0.05 m/s in next iteration

Conduction velocity: 0.0500 m/s [gi=25.0560, ge=90.0000, gm=19.5995]

No capture or decremental conduction, proximal quarter of tissue not fully activated

Any idea?

I'm using the latest version of openCARP.

Thanks,
