Comment (by Giuseppe Ficarra):

ScalarEvolve:

> In current version, in Scalar\_calc\_Tmunu, "compute\_fluxes==1" and "use\_jacobian=false" is not available....Should we add the comments in param file ?

Do you mean “use\_jacobian = true“? If you have a look at line 254 of Scalar\_calc\_Tmunu.F90, you can see that there is an if statement that uses the combination "compute\_fluxes==1" and "use\_jacobian=false". 

> in schedule, flux grid function is allocated, and Scalar\_zero\_densities is called when compute\_fluxes is true. But, in Scalar\_zero\_densities, flux grid functions are initialized only when use\_jacobian is false. So, if compute\_fluxes is true and use\_jacobian is true, flux grid function is not initialized.

fixed in  [https://bitbucket.org/canuda/scalar/commits/cb03ec3b4d1bd2e32787ffbf2d32f4dae2e13f27](https://bitbucket.org/canuda/scalar/commits/cb03ec3b4d1bd2e32787ffbf2d32f4dae2e13f27)
