Re: [fluka-discuss]: about material replace

Dear lichuanlong

your question is not really clear…Nevertheless, I’ll try to give you an answer based on my guess of what you mean...

With the present FLUKA version, it is only possible to change the material to VACUUM or BLACKHOLE for the transport of radioactive decay product.
You can refer to the documentation about WHAT(6) of the card ASSIGNMAt and to the related Note 5.

In case you need to change to a different material, you could implement a two-step method.
In the first step, you can dump the residual nuclei while in the second step you can load those nuclei in the "modified” geometry.

Hope this could help.

Cheers luigi
