FWD Software

Hi Daniel and all:

I am doing some tests on the FWD tracking code, but get some problems.
You can see the details in the slides below.
https://drupal.star.bnl.gov/STAR/system/files/fwd_20240120.pdf

One is that the reconstructed charge sign is flipped. Pi- is
reconstructed with a positive charge track, pi+ has negative charge.

Another problem is, there is a lot of time that I get below error
message when running BFC code. Especially when I try to produce the
pythia samples.
oot4star: .sl73_gcc485/obj/StRoot/StarMagField/StarMagField.cxx :1205:
static void StarMagField::Search(Int_t, const Float_t*, Float_t,
Int_t&): Assertion `! TMath::IsNaN(x)' failed. Abort

Any suggestions?

Thanks,
Ting
