Program PIC_MCC_for_CCP
   Use ParticleBundleModule 
   Implicit none
   
   TYPE(ParticleBundle) :: PBGlobal
   TYPE(ParticleOne2D) :: PBS(20)
   !Allocate(PBGlobal%PO,source=PBS)
   Allocate(ParticleOne1D::PBGlobal%PO(10))
   Call ParticleBundlePositionInitialization(PBGlobal)
   stop
end  Program  

 

I want to try some OOP features, so I want to have a Type, in which the type of some component will be dynamically allocated.I assumed with Class in the type particle bundle, PBGlobal%OS will be allocated as ParticleOne1D, but in two cases with source or type defined in the allocate, it still only allocate a array of ParticleOne. I think it is a bug of the compiler. Any one can helpl me with that problem? Thanks!

I am not seeing incorrect behavior when this program is compiled with version 17.0.1. When ParticleOneInitializationPosition is called for each element of component PO, the SELECT TYPE correctly chooses the ParticleOne1D case. What are you seeing instead and which compiler version are you using?

Perhaps it would help if you instrumented the code with PRINT statements that show the path it's taking.

Dear Steve

Thanks a lot for the help and quick reply, I just found that that the debug can not show the PO%X and PO%Y correctly, but PO%X and PO%Y have been correctly allocated and valued. It is not a compiler bug. Thanks a lot!
