Bug: ODEint fails with "Repeated convergence failures" when using EnergyTXTL

[zjurado]

When switching the simulation from SimpleTXTL to EnergyTXTL, the system fails to solve the differential equations and throws an ODEintWarning. The exact same model and setup simulate perfectly when using SimpleTXTL, but fail completely when the energy-dependent model is initialized.

ODEintWarning: Repeated convergence failures (perhaps bad Jacobian or tolerances). Run with full_output = 1 to get quantitative information.

odeint failed completely.

Can you post some code that generates this failure, so that we can confirm it occurs on other platforms. Ideally the example would be a "minimal" one that demonstrates this issue.

The complete script can be found in the Specialized Examples directory on my membrane_patch_Aug2026 branch Example 8. Multicellular_Transport.ipynb. The script is currently configured to use SimpleTxTlExtract.
