OmlCustomBlock for 1dof spring-mass model

Dear experts,

I built a very simple model in Activate using OmlCustomBlock that represents an 1dof spring-mass-damper model (see attched scm file). It works when SineWaveGenerator is used as a force, but not for Step Generator.

Please let me know what I should modify.

Hi Minoru,

I don't know why, but if you change the advanced parameter 'Activation mode' from 'Standard mode' to 'Always Active mode' the expected result is calculated.

Hi Minoru, Ronald,

The SineWave generator is a block that is an always active block. means that it is activated at every mesh point, discrete event, ...

The Step generator is only activated at initial time and at the step time.

The OmlCustomBlock when it is connected to those blocks and it is in standard mode, it inherits the Activations. So, in the case of the sinewave it will be always activated and in the case of the step it will be activated only twice. To make it always active you need to change the Activation mode in the block. In that case the block will be activated independently on the block that preceed.

Thanks

Fady

Ronald,

Thank you! We guessed that the problem related to activation, but I don't know that there is such an option in OmlCustomBlock.
