    Dear Hugo,

    Thank you for your guidance.

    1. One of my mistakes was that I did not know I should use a surface mesh for the visual model. Now I am using a surface mesh for visual model, however, again I can not see it in the run.
    This is the visual part of the xml code:

    <Node 	 name="node3"  >
			<OglModel template="ExtVec3f" name="visual"  fileMesh="d:/work/phd/sofa/liver/liverfinal/testbygmsh/livertriangle181.gmsh"  material="Default Diffuse 1 0.74902 0.74902 0 1 Ambient 1 0.2 0.2 0.2 1 Specular 0 1 1 1 1 Emissive 0 0 0 0 0 Shininess 0 45 "  primitiveType="DEFAULT"  blendEquation="GL_FUNC_ADD"  sfactor="GL_SRC_ALPHA"  dfactor="GL_ONE_MINUS_SRC_ALPHA" />
			<BarycentricMapping template="Vec3d,ExtVec3f" name="barycentricMap2"  input="@.."  output="@visual" />
			<MeshExporter name="meshExporter3"  filename="c:/users/zahra/desktop/livertrianglenew181.gmsh"  format="gmsh"  edges="0"  quads="0"  tetras="0"  hexas="0"  exportEveryNumberOfSteps="1"  exportAtBegin="1"  exportAtEnd="1" />
		</Node>

    2. Must I just use OBJexporter, or I can use other exporters such as meshexporter? (I prefer to have it in .gmsh format to avoid mesh converting).
    I use a high resolution mesh for behaviour model and a low resolution mesh for visual model.
    When I use MeshExporter to export the visual model, the number of nodes of visual model are equal to the number of nodes in the behaviour model. How can I have a low resolution visual model?

    3. You mean I should look at the force vector in mechanicalobject while I apply a force by mouse? It does not appear in the force vector. Should I export it somehow?

    for more information, here you can find the .scn and mesh files:

    Hi Guillaume,

    Thank you for your help. It seems that the “@” character in the scene file makes this problem as it is considered to be a contact message.

    Here is the scene file for the coarse simulation: https://titanpad.com/F0I5r0in3j

    The low-resolution mesh: https://gist.github.com/zbounik/1f7749322f1f53084a0740b97e20d80e
    The high-resolution mesh: https://gist.github.com/zbounik/908863a3c064069ad37c6bbe4d0ef955

    At a steady state, the deformation in the coarse simulation do not correspond to the fine simulation.

    In fact I expect the coarse simulation to drive the fine simulation. I would appreciate if you kindly give me some hints to solve this problem.

    Hi Hugo,

    Thank you for the quick reply and sorry for the delay in my response; I always try to go further based on your hints and then reply with more feedback.

    Yes I used v16.08 and I did not activate image plugin.
    Since your reply, I tried to build v16.12, and I activate flexible and image plugins. I received the following error:

    v16.12\src\applications\plugins\flexible\quadrature\GaussPointSmoother.h(60): error C2899: typename cannot be used outside a template declaration

    I fixed the problem by deleting the “typename” from the GaussPointSmoother.h, using the hint in the link below:

    http://stackoverflow.com/questions/19225458/error-c2899-typename-cannot-be-used-outside-a-template-declaration

    And sofa built successfully.

    Hi Guillaume,

    Yes, I added it. After the configuration, all paths relative to boost (including BOOST_INCLUDE_DIR) are truly added, except one for “Boost_DIR”. I added its path again, but after configuring, it again shows “Boost_DIR-NOTFOUND”.

    Any way, it is mentioned that SOFA includes miniboost, but without installing boost, cmake asks for installing it.

    Thanks for your help in advance,

    Hi Guillaume,

    I also have the same problem. I followed the documentation for building sofa. I am using Win 7, 64 bits- VS 2013- Qt 5.6, boost 1.6 and cmake 3.6.2. I also unzipped the external libraries folders into the source folder.

    There is no error in cmake. The project is built without any error, but I can not launch Runsofa and Modeler. When I try to launch Modeler I receive this error :

    boost_system-vc120-mt-gd-1_60.dll is missing from your computer. Try reinstalling the program to fix this problem.

    Dear Hugo,

    Yes it is really nice to hear that. I always feel the lack of such helpful documentation. Sometimes I just get some results without knowing the mathematical background and also the relation of components to each other.

    Can I have further details on the relation between “TriangularFEMForecefield”, “triangularBendingSprings”, “EulerImplicitSolver” and “CGLinearSolver”? More specifically, How “triangularBendingSprings” is related to the other components?

    Thank you very much for your support.

    Dear Hugo,

    Thank you for your help. I think something is wrong in my scene. When I apply your suggestion, it is unsaved when I reopen the VTKExporter. I should put a time to figure out the problem. I will let you know as soon as I succeed.

    Dear Hugo,

    Thank you for your kind reply.

    I link the “PointsDataFields” in VTKExporter to the “force” data in my MechanicalObject by this command: “@MechObj.force”. But VTKExporter again exports the positions and not the forces.
    Do I use a true procedure or Should I make any other changes?

    Thank you.

    Dear Hugo,

    Thank you for following up and Sorry for the late reply, other problems distracted me for a while.

    No I am still looking for it. What I mean by force field is the force that is applied to each node. I think it is the same force I can see in the run window by checking forcefields. Using VTK exporter and choosing PointsDataFields gives me the positions of the nodes and not the forces, or maybe I still do not know how to use it correctly for my purpose.

    1. This component is not in my SOFA components. Which option in cmake should I choose to build this component?

    2. My mesh is so high resolution, and I want to drag the same vertice to exactly the same certain extent each time that I animate the scene. Using Shift+click behaviour allows to drag every vertice to every extent.

    Dear Alex,

    Thank you for your reply. Yes my second question was related to the first one. I do not have any knowledge on Python, so, Based on your suggestion I added StiffSpringForceField component to the root node, however I do not know how to add the rest and initial position in the component.

    1. In Index property, I can insert just one value for each index. How can I insert (x,y,z) positions of desired points in StiffSpringForceField’s property? For example, how can I define a spring with one end on the (x,y,z)=(0,0,0) from the planeforcefield and the other end on (x,y,z)=(0,0,1) of my deformable object?

    2. If I want to define another spring between a point on my object and the 3D position of the mouse, how and where should I define the 3D position of the mouse?

    Best,

    Zahra
