lvm voltage input problem

[goodtimesblues]

Hi there, I am trying to import a simple voltage profile in a lvm file (made by a NI 6009 USB DAQ), and run it through a simple rectifier:

I attached a pic of the circuit.  If I disconnect the rectifier I do get the correct profile from the voltage.  When the rectifier is connected (as in the pic)n the input voltage and after rectifier voltage can be seen on the oscilloscope for one cycle, then when they converge at 0, I get a simulation error.  I run the Convergence Assistant but it fails..  If I put an AC source component instead of the lvm input component the circuit works fine.  Hmm sure hope someone can help.  I can send the lvm and multisim files if needed.

Thanks,

David

Hi David,

Please attach the Multisim and the lvm file.

Here are the files:

Thanks,

I had to send the lvm file as txt.  FOr some reason lvm was not valid for an attachment.

Hi David,

You are missing a ground in your circuit, the SPICE engine must have a node zero somewhere in the circuit.

Ok I'll try that.  Thanks!
