Wall interface.
This is an interface through which wall data is initialized and accessed. Reading e.g. from disk is done elsewhere.
To add a new wall instance, make sure these functions are implemented and called from this interface, and that wall.h contains enum type for the new instance.
The interface checks which instance given data corresponds to from the "type"-field in wall_offload_data or wall_data that is given as an argument, and calls the relevant function for that instance.
Definition in file wall.c.
| int wall_init_offload | ( | wall_offload_data * | offload_data, |
| real ** | offload_array, | ||
| int ** | int_offload_array ) |
Load wall data and prepare parameters.
This function fills the relevant wall offload struct with parameters and allocates and fills the offload array. Sets offload array length in the offload struct.
The offload data has to have a type when this function is called as it should be set when the offload data is constructed from inputs.
This function is host only.
| offload_data | pointer to offload data struct |
| offload_array | pointer to pointer to offload array |
| int_offload_array | pointer to pointer to offload array storing integers |
| void wall_free_offload | ( | wall_offload_data * | offload_data, |
| real ** | offload_array, | ||
| int ** | int_offload_array ) |
Free offload array and reset parameters.
This function deallocates the offload_array.
This function is host only.
| offload_data | pointer to offload data struct |
| offload_array | pointer to pointer to offload array |
| int_offload_array | pointer to pointer to offload array storing integers |
| int wall_init | ( | wall_data * | w, |
| wall_offload_data * | offload_data, | ||
| real * | offload_array, | ||
| int * | int_offload_array ) |
Initialize wall data struct on target.
This function copies the wall parameters from the offload struct to the struct on target and sets the wall data pointers to correct offsets in the offload array.
| w | pointer to data struct on target |
| offload_data | pointer to offload data struct |
| offload_array | pointer to offload array |
| int_offload_array | pointer to pointer to offload array storing integers |
| int wall_hit_wall | ( | real | r1, |
| real | phi1, | ||
| real | z1, | ||
| real | r2, | ||
| real | phi2, | ||
| real | z2, | ||
| wall_data * | w, | ||
| real * | w_coll ) |
Check if a given directed line segment intersects the wall.
This function is intended to be used to check whether a marker collides with the wall. If there is a collision, this function returns an identification number specific to that wall tile. If the marker hits multiple wall elements, only the first one is returned.
This is a SIMD function.
| r1 | start point R coordinate [m] |
| phi1 | start point phi coordinate [rad] |
| z1 | start point z coordinate [rad] |
| r2 | end point R coordinate [m] |
| phi2 | end point phi coordinate [rad] |
| z2 | end point z coordinate [rad] |
| w | pointer to data struct on target |
| w_coll | pointer for storing the parameter in P = P1 + w_coll * (P2-P1), where P is the point where the collision occurred. |
