Dear All,

Does anyone know if it would be possible to plot history locations for histories created using FISH (e.g. acceleration of a structural node as shown below)?

fish define get\_node1  
\_node1 = struct.node.find(1)  
end  
@get\_node1  
fish define \_acceleration1x  
\_acceleration1x = struct.node.acc.global(\_node1,1)  
end  
fish history \_acceleration1x

Thank you so much.

You can write a small FISH function to define user-define scalars at the history positions,  
then plot User-Defined Data → Scalars:

> fish define Hist\_Location  
> local s = data.scalar.create(struct.node.pos( \_node1))  
> data.scalar.value(s) = 1.0 ; value not important  
> end  
> [Hist\_Location]

Thank you so much indeed Zhao, it is much appreciated.
