| void allocate_field | ( | struct Field * | fldi | ) |
Allocate a field structure according to the code current configuration This routine allows one to add extra fields to the code very easily.
| *fldi,: | pointer to a field structure to initialize |
Here is the caller graph for this function:| float big_endian | ( | float | in_number | ) |
Determines if the machine is little-endian. If so, it will force the data to be big-endian.
| in_number | floating point number to be converted in big endian |
Here is the caller graph for this function:| void deallocate_field | ( | struct Field * | fldi | ) |
Deallocate a field structure created by allocate_field
Here is the caller graph for this function:| double energy | ( | const double complex | q[] | ) |
Compute the energy of a given field.
| q | complex array containing the field for which we want the total energy |
Here is the caller graph for this function:| void finish_common | ( | void | ) |
Here is the caller graph for this function:| double get_c_time | ( | void | ) |
Return the localtime in seconds. Use different implementation depending on the avaiable libraries
Here is the caller graph for this function:| void init_common | ( | void | ) |
Init all global variables, aligning them in memory
Here is the caller graph for this function:| void projector | ( | double complex | qx[], |
| double complex | qy[], | ||
| double complex | qz[] | ||
| ) |
Remove the divergence from a 3D field using the projector operator: q=q-k.q/k^2
| qx,: | x component of the field |
| qy,: | y component of the field |
| qz,: | z component of the field |
Here is the caller graph for this function:| double randm | ( | void | ) |
Customized random number generator Allow one to have consistant random numbers generators on different architectures.
Here is the caller graph for this function:| double randm_normal | ( | void | ) |
Normal distribution Algorithm by D.E. Knut, 1997, The Art of Computer Programmin, Addison-Wesley.
Here is the call graph for this function:| void reduce | ( | double * | var, |
| const int | op | ||
| ) |
Reduce a variable over all the avaiable processes Can add a value on all the process, find a maximum or a minimum.
NOTE: This routine makes sense only when MPI_SUPPORT is set. If not, this routine does nothing.
| *var,: | variable to be reduced |
| op,: | operation needed to be done. Can be set to: 1= Sum over all the processes 2= Find the maximum over all the processes 3= Find the minimum over all the processes |
Here is the caller graph for this function:| double * ik2t |
inverse of k2t Wavevector, function of time when SHEAR is present. set to 0 wheh k2t=0 to avoid singularity
| double * k2t |
k squared Wavevector, function of time when SHEAR is present.
| double kmax |
Maximum wavevectors
| double* kx |
x Wavevector
| double kxmax |
| double * kxt |
Time dependant x Wavevector. Different from kx only when SHEAR is present.
