Dear Riya,
thank you for your questions. I have attached a modified version of your input file were your questions are implemented.
"1. If we want to create two replicas of target3, can it be done using single transform card and single lattice card?"
I believe this is not possible due to the fact that for each replica there can be only one unique transformation pointing to the original prototype. So the same prototype needs a unique transformation for each replication.
"2. Now, I want to replicate target1 also. Is it possible to replicate these two target cards (target1 and target3) using single transform card and single lattice card ?"
This is indeed possible but only if the replicas are transformed "equally". E.g. if both replicas need to be just +20cm to the z axis.
3. What is the difference between transform card and lattice card?
A transformation card is by no means related to the lattice card. The transformation card is useful for a number of different occasions were transformation of bodies, usrbins etc. are needed.
The lattice card is there to indicate that a certain region should be considered as a lattice region and it provides the information needed for the correct transformation of particles to the prototype. I.E. the transformation using a certain rot-defi card or a series of rot-defi cards etc.
"4. How to assign materials in the replicated region?"
You can in principle assign any material or no material at all. Anyway the code knows that the region is considered a lattice and therefor ignores the material of the specific region and only considers the geometry of the prototype.
"5. If new lattices are created using lattice card, how to get the USRBIN scoring in those lattice regions since in the USRBIN card, these lattice names are not appearing?"
Spacial USRBINs work as normal with lattices since they are overlaid on top of the geometry, so there is nothing special needed.
USRBINs that are per region will score the addition of the relevant quantities in both the prototype and the replicated regions.
If you want to extract separately the information of each lattice then you can use the "special binning" option What(1)= 8 or 18 (please see manual for the other what values in this case).
Hope this helps
Kind regards

Subject: [fluka-discuss]: DOUBTS REGARDING LATTICE CARD IN FLUKA
Dear FLUKA Experts,
I have some doubts regarding creating geometry with the help of LATTICE card. A simple input is attached here. Here I have created two target regions, namely, taget1 and target3. When I want to create a replica of target3, I have used transform card at the same location where target3 is situated and named that region as replica3. Then I have used LATTICE card for the region replica3
Now, my questions are:
1. If we want to create two replicas of target3, can it be done using single transform card and single lattice card?
2. Now, I want to replicate target1 also. Is it possible to replicate these two target cards (target1 and target3) using single transform card and single lattice card ?
3. What is the difference between transform card and lattice card?
4. How to assign materials in the replicated region?
5. If new lattices are created using lattice card, how to get the USRBIN scoring in those lattice regions since in the USRBIN card, these lattice names are not appearing?
Thanks and Regards
Riya Dey
