| Option |
Default |
Description |
| hand_guided_tearing |
True |
If enabled, hand guided tearing of equation system is performed. |
| generate_html_diagnostics |
False |
If enabled, model diagnostics are generated in HTML
format. This includes the flattened model, connection
sets, alias sets and BLT form. |
| equation_sorting |
True |
If enabled, then the equation system is separated into
minimal blocks that can be solved sequentially. |
| expose_scalar_equation_
blocks_in_interactive_fmu |
True |
If enabled, unsolved scalar equations will be exposed to
the external solver when generating interactive fmu. |
| divide_by_vars_in_tearing |
True |
If enabled, a less restrictive strategy is used for solving
equations in the tearing algorithm. Specifically, division
by parameters and variables is permitted, by default no
such divisions are made during tearing. |
| merge_blt_blocks |
True |
If this option is set to true (default is false), BLT
blocks will be constructed so that all level one HGT pairs
and all unpaired HGT will reside inside the same BLT
block. |
| automatic_tearing |
True |
If enabled, then automatic tearing of equation systems is
performed.
|
| variability_propagation |
False |
If enabled, the compiler performs a global analysis on the
equation system and reduces variables to constants and
parameters where applicable.
|
| interactive_fmu |
True |
If enabled, the DAE system is converted into an interactive fmu where all residual equations and iteration variables have been changed into top level outputs and inputs. |
| index_reduction |
False |
If enabled, then index reduction is performed for high-index systems |
| local_iteration_in_tearing |
annotation |
This option controls whether equations can be solved local in tearing. Possible options are: 'off', local iterations are not used (default). 'annotation', only equations that are annotated are candidates. 'all', all equations are candidates
|
| include_protected_variables |
False |
Includes protected variables in the compilation target interface if the protectionannotation on the class allows
viewing variables. |
| c_compiler |
gcc |
The C compiler to use to compile generated C code.
|
| Option |
Default |
Description |
| max_iter_no_jacobian |
1 |
Maximum number of iterations without jacobian update. Value 1 means an update in every iteration. [1, 1000] (Corresponding compiler option:
nle_solver_max_iter_no_jacobian) |
| tolerance |
0.00001 |
Relative tolerance [eps(1), 0.1]. (Corresponding compiler
option: nle_solver_default_tol)
|
| step_limit_factor |
1 |
Factor used to limit the step size based on nominal and
min/max range [0.01, 100]. Newton step length is limited
so that for any iteration variable xi it is not larger than
step_limit_factor times min(max(abs(nominal),
abs(xi)),(xi_max-xi_min)). (Corresponding compiler option: nle_solver_step_limit_factor)
|
| jacobian_calculation_mode |
9 |
Mode for how to calculate the Jacobian: 0 - onesided differences, 1 - central differences, 2 - central differences at
bound, 3 - central differences at bound and 0, 4 - central
differences in second Newton solve, 5- central differences
at bound in second Newton solve, 6 - central differences
at bound and 0 in second Newton solve, 7 - central differences when small residual, 8 - calculate Jacobian through
MATLAB®, 9 - Jacobian compression. (Corresponding
compiler option: nle_jacobian_calculation_mode)
|
| residual_equation_scaling |
5 |
Residual equation scaling mode: 0 - no scaling, 1 - automatic scaling, 2 - manual scaling, 3 - hybrid scaling,
4 - aggressive automatic scaling, 5 - automatic rescaling
at full Jacobian update. (Corresponding compiler option:
residual_equation_scaling)
