variable call back into an array

[yamifm0f]

Hello

I would like to get the value of each port area in a pipe in one array. I have developed an array class called Equation where equation.A is an array and equation.c is a vector
I want to assign the value for each area in a different script and then add it to the main program in the array.
so far I have no luck in getting this to work. any help or advice will be appreciated.


This is the main program

import numpy as np
import sys

uCounter = 0

class Pipe(object):
   global uCounter

   def __init__(self, nPorts, volume):
      self.volume = volume
      self.nPorts = nPorts  
      self.freePorts = [] #The ports of the pipe that are not in use 
      self.portSetAreas = []  
      self.portSetAreasValue = [] 
      for i in range(nPorts):
         self.freePorts.append(i)
         self.portSetAreas.append(False)
         self.portSetAreasValue.append(0.0)
      self.Areas = D(self.nPorts)               # where D refers to the domain and how many ports it contain 
      self.pd = np.zeros((self.nPorts))
      self.dt = 0.0  

   def logics(self):
       nFree = len(self.freePorts)
       for port in range(nFree):
          if self.portSetAreas[self.freePorts[port]]:
             self.Areas = self.portSetAreasValue[self.freePorts[port]]  

   def Values1(self):
      equation = Equation(1, uCounter)          #where Equation is an array class 
      for p in range(self.nPorts):              #nPorts is the number of ports with an area 
         equation.A[0, self.m.gid[p]] = self.Areas[p] #the multible values of the Area will be put into an array equation.A
      equation.c[0] = 0.0                       #This is a vector 
      return(equation)

#the problem is with self.Areas[p] this multible values will be called form anoth script "test1"

This is the test1 script

import math
import numpy as np
import sys
import scipy.io
import mainproject

Pipe1.portSetAreas[0] = True
Pipe1.portSetAreasValue[0] = 0.1
Pipe1.portSetAreas[1] = True
Pipe1.portSetAreasValue[1] = 0.1

#0 refer to the inlet of the pipe
#1 refer to the outlet of the pipe

Error:
equation.A[0,self.m.gid[p]] = self.Areas
TypeError: float() argument must be a string or a number

You should debug your code.
Then you will see that the argument
is neither a string nor a number.
Probably it will be "None".

What I need is to know how to put a condition for the value of Areas
so if there is an Area at port 0 the value will be 0.1
if there is an Area at port 1 the value will be 0.2

I need this to be here

 def Values1(self):
      equation = Equation(1, uCounter)          #where Equation is an array class 
      for p in range(self.nPorts):              #nPorts is the number of ports with an area 
         equation.A[0, self.m.gid[p]] = self.Areas[p] #the multible values of the Area will be put into an array equation.A
      equation.c[0] = 0.0                       #This is a vector 
      return(equation)

in the self.Areas[p]

if I can do this my problem will be resolved.

Sorry, I can not help, your code is too complex.
