Hey @Hugo,

Sorry for responding so late, but I indeed managed to reset the scene by re-initializing the state vectors of the MechnicalObject.

Thanks a lot for the help.

Best Regards,
Agniv.

Dear @hugo,

One more update, I tried to reset the mechanical object using:

self.myMechanicalObjectPointer.reset()

However, it still seems like the model is slowly converging back to the neutral configuration. The surface of the object slowly oscillates back to rest.

Regards,
Agniv.

Dear @Hugo

I am trying to apply a small force to a specific node along X, Y and Z axis…. and study the result of the application of this force on the object.

Given the object in its rest configuration, I apply Delta F_x, Delta F_y and Delta F_z on the node. This produces three different output, which I capture using the OBJExporter script. I…[Read more]

Hi Hugo,

Stripping down the code to the basics, and using the CMakeLists.txt you suggested results in the following compilation error:

/usr/bin/ld: cannot find -lSofaComponentCommon
collect2: error: ld returned 1 exit status
CMakeFiles/Sofa.dir/build.make:130: recipe for target 'Sofa' failed
make[2]: *** [Sofa] Error 1

@egarcm Ah! Yes, those fields are empty, indeed!

Did you figure out a workaround? Is that actually the root cause?

(What OS are you using, btw? I have a suspicion, the interaction between TinyXML and Ubuntu 17 might be going wrong in my case!)

Hi @egarcm,

Do you mean sofa_scene/build/CMakeCache.txt ?

I do not have those strings in that file! In a fresh build, I do not have nearly as many lines as that.

Hi,

My CMakeLists.txt, in the SOFA scene project, now reads:

cmake_minimum_required(VERSION 3.1)
project(Sofa)

add_executable(${PROJECT_NAME} Main.cpp)
target_link_libraries(${PROJECT_NAME} SofaComponentCommon)

I ran make and sudo make install…[Read more]

The same code as given in: the demo.

I do not want Main.cpp to do much, as of now. I just want it to compile with full functionality, so that I can play around with it, and eventually do a FEM simulation of sorts.

If I link it with just SofaComponentCommon, I get a different output:

CMake Warning at CMakeLists.txt:7 (find_package):
By not providing "FindSofaComponentCommon.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"SofaComponentCommon", but CMake did not find one.

Could not find a…[Read more]

I changed the cmake file to:

cmake_minimum_required(VERSION 3.1)
project(Sofa)

add_executable(${PROJECT_NAME} Main.cpp)
target_link_libraries(${PROJECT_NAME} SofaFramework SofaComponentCommon)

Looks like that worked!…[Read more]

So I change the Cmake file to:

cmake_minimum_required(VERSION 3.1)
project(Sofa)

add_executable(${PROJECT_NAME} Main.cpp)
target_link_libraries(${PROJECT_NAME} SofaFramework SofaComponentCommon)

This still does not work!

How do I do that? I tried setting SofaFramework_DIR to the build path, but that did not work.

Hi,

I have tried to build the demo scene. Here’s what I do:

I have the following directory structure:

sofa_scene
|
+—>build/
|
+—>CMakeLists.txt
|
+—>Main.cpp

The Main.cpp is an exact copy from the tutorial.

The CMakeLists.txt contains:

cmake_minimum_required(VERSION 3.1)
project(sofa_scene)

find_package(SofaFramework…[Read more]

I have the following folders in examples/Tutorials/ folder:

Basic
Collision
ForceFields
Mappings
OldTutorials
sandbox
Solvers
StepByStep
Topologies

But none of them seem to contain any cpp files.

I do understand how to create a simple scene using XML and to solve it. But how do I do the same using cpp?

Best,
Agniv.
