Comment (by 池田大志):

Hi, I checked the thorn, and I have several comments. Now, there is not test case, my comment is only about code now. Since I am checking development branch, the line and file name are based on development branch.

In ScalarBase,

• In line 16th in param.ccl in ScalarBase, we should add absolute value for phi.

• The description of parameters lEF and mEF in param.ccl is misleading. Current version supports only (lEF,mEF)=(0,0), (1,1), (2,2) and not (1,0),(2,0), (2,1). (see 68th line in Scalar_rhs_forcing.F90)

• Is there information about external force as document ? I can not find it.

In ScalarEvolve,

• In ScalarEvolve, why BSSN-like variables are public ? Since same name variables are used in other thorn (like lean_public) and they are just auxiliary field to calculate rhs of the equations, private is better for them.

• In Scalar_calc_Tmunu.F90, in Scalar_calc_Tmunu, xx and rr should be private in OpenMP in grid loop.

• 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 ?

• In Scalar_ord4_calc_rhs.F90, line 638th and 639th (def sn1 and sn2) can be outside grid loop ? or should the excision procedure be separated as independent thorn ?

• Also, Rout_excision1, Rout_excision2, Rin_excision1, Rin_excision2 can be outside grid loop ?

• 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.

In ScalarInit

• In ID_SF_BS, bh mass assumed to be one ? There is parameter m_plus, but, it is not used appropriately.... for example, line 40th and 41th.

• I
