FMI4cpp is a cross-platform [FMI](https://fmi-standard.org/) 2.0 implementation written in modern C++.
Influenced by its spiritual brother [FMI4j](https://github.com/NTNU-IHB/FMI4j), it aims to be
an easy to install, easy to use, object-oriented and fast FMI implementation for C++.
FMI4cpp supports both **Co-simulation** and **Model Exchange**.
### Why should I use this over other C/C++ FMI Libraries
Because it provides a clean, easy to use API and is easy to install.
It performs just as good as FMI Library, provides more features and is significantly easier to both build and use.
## Install instructions
Refer to [INSTALL.md](INSTALL.md)

#### API
```cpp
#include
#include
using namespace fmi4cpp;
const double stop = ...;
const double stepSize = ...;
int main()
{
fmi2::fmu fmu("path/to/fmu.fmu");
auto cs_fmu = fmu.as_cs_fmu();
auto me_fmu = fmu.as_me_fmu();
auto cs_md = cs_fmu->get_model_description(); //smart pointer to a cs_model_description instance
std::cout << "model_identifier=" << cs_md->model_identifier << std::endl;
auto me_md = me_fmu->get_model_description(); //smart pointer to a me_model_description instance
std::cout << "model_identifier=" << me_md->model_identifier << std::endl;
auto var = cs_md->get_variable_by_name("my_var").as_real();
std::cout << "Name=" << var.name() << ", start=" << var.start().value_or(0) << std::endl;
auto slave = cs_fmu->new_instance();
slave->setup_experiment();
slave->enter_initialization_mode();
slave->exit_initialization_mode();
double t;
double value;
auto vr = var.valueReference();
while ( (t = slave->get_simulation_time()) <= stop) {
if (!slave->step(stepSize)) {
std::cerr << "Error! step() returned with status: " << to_string(slave->last_status()) << std::endl;
break;
}
if (!slave->read_real(vr, value)) {
std::cerr << "Error! step() returned with status: " << to_string(slave->last_status()) << std::endl;
break;
}
std::cout << "t=" << t << ", " << var.name() << "=" << value << std::endl;
}
slave->terminate();
return 0;
}
```
