[moose-devel] Sending data to the Shell via HSolve

[Saeed S. <sa...@gn...>]

Dear all,

I'm trying to send Vm to the shell and according to the HSolve
implementation, the value sets via the below mechanism:

moose::Compartment::VmOut()->send(compartmentId.eref(), newVm);

In the first glance, I thought that just by calling this method, in any
place, we can change internal representation of Vm in the Shell and the
output mechanism can read it via clock mechanim.

But, for example when I send an specific value via this message, there is
no change in the output in Python. Would you please guide me about the I/O
mechanism in shell and also that command is the only thing that provides
output?

Thank you,
Saeed

Dear Saeed,
     Unclear what you wish to do. There is a set of access functions 
from Python to retrieve field values. For a compartment on 
'/model/compt' you would do

x = moose.element( '/model/compt' )
print x.Vm

if you want to access the value from the Python shell. The snippets in 
Demos/snippets have many examples.

If on the other hand you want to do a low-level transfer of information 
between MOOSE objects, you can use the message sending mechanism below, 
but the data will only go to objects which have been connected up 
through message creation functions. There are examples of this also in 
the snippets.

Best,
     Upi

Re: [moose-devel] Sending data to the Shell via HSolve

[Saeed S. <sa...@gn...>]

Dear Upi,

In low level. I am developing a MasterHSolve to replace with the current 
HSolve and deals with batch of neurons for GPU+CPU.

I tried to send data to the Shell for generating output, but my sending 
does not affect the output. My question is: Does the Shell keep an 
internal presentation for each object and for input we should change it? 
and what is the best method if a solver wants to generate output? (I 
mean standard outputs same as Table object)

Thanks,
     Saeed

Dear Saeed,
     Please look at the snippets regarding message passing. This is used 
when during runtime you need to send data to one ore more objects. I 
stress that this should NOT be used for sending data to the Python shell.

It might help for you to write some pseudocode to indicate what it is 
you are trying to do, and why.

Best,
     Upi

Dear Upi

I will look at snippets and if I could not sovle the issue, I will ask 
with details.
Thank you for your time.
