EVtwin throws for stars with M>20 Msun

[eichryso]

Hello all!

It seems like I cannot use EVtwin for stars more massive than 20 Msun. I run the following script:

from amuse.units import units from amuse.community.evtwin.interface import EVtwin from amuse.datamodel import Particle from amuse.ext.star_to_sph import convert_stellar_model_to_SPH

mass = 30 | units.MSun age = 3.5 | units.Myr n_particles = 1000

stellar_evolution = EVtwin() star = Particle(mass=mass)
se_star = stellar_evolution.particles.add_particle(star) se_star.evolve_for(age)

sph_particles = convert_stellar_model_to_SPH(se_star, n_particles).gas_particles stellar_evolution.stop()

and i get an amuse exception error: Error when calling 'evolve_for' of a 'EVtwin', errorcode is -1002. When I tried the same code using a smaller mass of 10Msun it run just fine. Is this a problem of the EVtwin code?

Thanks in advance, Eirini

Hi Eirini,

The developers of EVTwin inform me that it's simply not designed to deal with such heavy stars, so it's not you. It would be nice if it gave a better error message though, so let's leave this issue open and take it as a request for better documentation.
