walberla::mesa_pd::kernel::SemiImplicitEuler Class Reference

Detailed Description

Semi-implicit Euler integration for position and velocity.

This kernel requires the following particle accessor interface

const walberla::mesa_pd::Vec3& getPosition(const size_t p_idx) const;
void setPosition(const size_t p_idx, const walberla::mesa_pd::Vec3& v);
 
const walberla::mesa_pd::Vec3& getLinearVelocity(const size_t p_idx) const;
void setLinearVelocity(const size_t p_idx, const walberla::mesa_pd::Vec3& v);
 
const walberla::real_t& getInvMass(const size_t p_idx) const;
 
const walberla::mesa_pd::Vec3& getForce(const size_t p_idx) const;
void setForce(const size_t p_idx, const walberla::mesa_pd::Vec3& v);
 
const walberla::mesa_pd::data::particle_flags::FlagT& getFlags(const size_t p_idx) const;
 
const walberla::mesa_pd::Rot3& getRotation(const size_t p_idx) const;
void setRotation(const size_t p_idx, const walberla::mesa_pd::Rot3& v);
 
const walberla::mesa_pd::Vec3& getAngularVelocity(const size_t p_idx) const;
void setAngularVelocity(const size_t p_idx, const walberla::mesa_pd::Vec3& v);
 
const walberla::mesa_pd::Mat3& getInvInertiaBF(const size_t p_idx) const;
 
const walberla::mesa_pd::Mat3& getInertiaBF(const size_t p_idx) const;
 
const walberla::mesa_pd::Vec3& getTorque(const size_t p_idx) const;
void setTorque(const size_t p_idx, const walberla::mesa_pd::Vec3& v);

Precondition

All forces and torques acting on the particles have to be set.

Postcondition

All forces and torques are reset to 0.
