Hello,
I will create a new CFD model based on Aneurysm example and have 2 questions about the constraint of outvar ‘integral_continuity’.
*Environment
Simnet version : 21.06
*Questions

Is the value of ‘integral_continuity’ calculated in IntegralContinuity.make_node() in navier_stokes.py?
If it was wrong, please let me know where it is calculated. 
Why is the constraint value of ic_2 integral_continuity negative(2.540) as line 119 in aneurysm.py?
I think the value should be positive(2.540) so that it is equivalent as ic_1.

112 # Integral Continuity 1
113 ic_1 = outlet_mesh.boundary_bc(outvar_sympy={‘integral_continuity’: 2.540},
114 lambda_sympy={‘lambda_integral_continuity’: 0.1},
115 batch_size_per_area=128)
116 self.add(ic_1, name=“IntegralContinuity_1”)

118 # Integral Continuity 2
119 ic_2 = integral_mesh.boundary_bc(outvar_sympy={‘integral_continuity’: 2.540},
120 lambda_sympy={‘lambda_integral_continuity’: 0.1},
