Thank you Timo, I will look into it today, following the link provided by

control on what happens within the main simulation loop, but for now I'm stuck
with 2.12, which is also good code.

Hi Edscott,
why would it reduce to 2p? You can still have deformations inside the domain.
Formulation was changed from the default to pNsW. And the fluidsystem was
changed to the oil/water fluidsystem used a working 2p problem.
The boundary conditions are set to:
void boundaryTypesAtPos(BoundaryTypes , const GlobalPosition&
globalPos) const
{
values.setDirichlet(uxIdx);
values.setDirichlet(uyIdx);
Scalar top = this->bBoxMax()[1];
Scalar bottom = this->bBoxMin()[1];
if (globalPos[1] > top - eps_)
{
values.setDirichlet(pressureIdx); // nonwetting pressure
values.setOutflow(Indices::contiNEqIdx);
}
else // Neumann for the remaining boundaries
values.setAllNeumann();
}
void neumannAtPos(PrimaryVariables , const GlobalPosition&
globalPos) const
{
if (globalPos[1] < eps_)
{
auto wflow = -1.37e-3; // water flow at bottom
values[Indices::contiWEqIdx] = wflow;
values[Indices::contiNEqIdx] = 0; // oil flow at bottom
} else {
// no-flow on the remaining Neumann-boundaries.
values[Indices::contiWEqIdx] = 0;
values[Indices::contiNEqIdx] = 0;
}
}
void dirichletAtPos(PrimaryVariables , const GlobalPosition&
globalPos) const
{
values = 0.0;
Scalar top = this->bBoxMax()[1];
Scalar bottom = this->bBoxMin()[1];
Scalar right = this->bBoxMin()[0];
if (globalPos[1] > top - eps_){
values[Indices::pressureIdx] = 1.72e7;
}
}
Since "void initialAtPos(PrimaryVariables , const GlobalPosition
)" is ignored, the initial pressure is set withinitial pressure is
set with:
void initializePressure()
{
for(const auto& vertex : vertices(gridView_))
{
int vIdxGlobal = this->vertexMapper().index(vertex);
GlobalPosition globalPos = vertex.geometry().corner(0);
// initial approximate pressure distribution at start of
initialization run
pInit_[vIdxGlobal] = -1.72e7;
}
}
Gravity is disabled so depthBore should not have any effect.
Expected result: Should reproduce the 2p flow problem.

I’ve kind of given up on this approach. What I want to try next is to create a
multiprocess run, with an elastic model coupled sequentially with a 2p model.
The first process will solve for the deformations (preferably with the el2p
pdelab formula). This should give me a pressure distribution in the grid. Then
use this pressure distribution to feed a 2p model for a single iteration with
an outflow condition. This would have to spin until pressure converges. Once
that happens, go back to the elastic and start again.
Basically all I want to do for the moment is to emulate a Mandel problem, where
we have a constant vertical pressure on top, no flow on the bottom and on the

Re: [DuMuX] using el2p with fluid flow
I’ve kind of given up on this approach. What I want to try next is to create a
multiprocess run, with an elastic model coupled sequentially with a 2p model.
The first process will solve for the deformations (preferably with the el2p
pdelab formula). This should give me a pressure distribution in the grid. Then
use this pressure distribution to feed a 2p model for a single iteration with
an outflow condition. This would have to spin until pressure converges. Once
that happens, go back to the elastic and start again.
Basically all I want to do for the moment is to emulate a Mandel problem, where
we have a constant vertical pressure on top, no flow on the bottom and on the
left, no vertical deformation on the left side and no horizontal deformation on
the bottom. The right side is left open both the deformation and fluid flow.
Fluid will be squished out.

I'm trying to use the el2p example program to construct a program with
inflow/outflow. In order to test the feasibility, after simplifying to 2
dimensions instead of 3, I have used the data from a working problem with the
2p model. On the first test, set the boundary conditions allDirichlet for uxIdx
and uyIdx and equal to zero. This would be equivalent to null elasticity and
the model should reduce to the 2p model.
Hi Edscott,
why would it reduce to 2p? You can still have deformations inside the domain.
Formulation was changed from the default to pNsW. And the fluidsystem was
changed to the oil/water fluidsystem used a working 2p problem.
The boundary conditions are set to:
void boundaryTypesAtPos(BoundaryTypes , const GlobalPosition&
globalPos) const
{
values.setDirichlet(uxIdx);
values.setDirichlet(uyIdx);
Scalar top = this->bBoxMax()[1];
Scalar bottom = this->bBoxMin()[1];
if (globalPos[1] > top - eps_)
{
values.setDirichlet(pressureIdx); // nonwetting pressure
values.setOutflow(Indices::contiNEqIdx);
}
else // Neumann for the remaining boundaries
values.setAllNeumann();
}
void neumannAtPos(PrimaryVariables , const GlobalPosition&
globalPos) const
{
if (globalPos[1] < eps_)
{
auto wflow = -1.37e-3; // water flow at bottom
values[Indices::contiWEqIdx] = wflow;
values[Indices::contiNEqIdx] = 0; // oil flow at bottom
} else {
// no-flow on the remaining Neumann-boundaries.
values[Indices::contiWEqIdx] = 0;
values[Indices::contiNEqIdx] = 0;
}
}
void dirichletAtPos(PrimaryVariables , const GlobalPosition&
globalPos) const
{
values = 0.0;
Scalar top = this->bBoxMax()[1];
Scalar bottom = this->bBoxMin()[1];
Scalar right = this->bBoxMin()[0];
if (globalPos[1] > top - eps_){
values[Indices::pressureIdx] = 1.72e7;
}
}
Since "void initialAtPos(PrimaryVariables , const GlobalPosition
)" is ignored, the initial pressure is set withinitial pressure is
set with:
void initializePressure()
{
for(const auto& vertex : vertices(gridView_))
{
int vIdxGlobal = this->vertexMapper().index(vertex);
GlobalPosition globalPos = vertex.geometry().corner(0);
// initial approximate pressure distribution at start of
initialization run
pInit_[vIdxGlobal] = -1.72e7;
}
}
Gravity is disabled so depthBore should not have any effect.
Expected result: Should reproduce the 2p flow problem.
why?
Result: Segment violation crash. This is the gdb output following compilation
with -O0.
Looks like the fluid state is uninitialized. Did you debug and check why it is
uninitialized? Is the error in Dumux code (does it occur in an unmodified
setup)? You seem to use a custom fluid system with a member function
“saturation()”?! It’s not clear to me why any fluid system should have such a
function...
