Multi-turn coil into simple SPICE circuit

Hi,

I have recently downloaded and played around with the COMSOL model "Inductor in an amplifier circuit" (www.comsol.no/model/inductor-in-an-amplifier-circuit-990). This worked well, but when adding my own NETLIST from a simple circuit (picture attached), I get various error messages from the time dependent solution. (Reach singularity, maximum number of iterations reached, failed to find solutions for all parameters and so forth).

I have attached my model file and hope that someone with more experience than me can point me in the right direction and increase my knowledge about this extremely powerful tool.

NETLIST below:

*
R1 N002 0 10MEG
*L1 N001 N002 244µ (this is the inductor i removed from the circuit and replaced with the COMSOL multi-turn coil)
R2 N002 N003 59.4
C1 N003 0 138n
V1 N001 0 PULSE(0 813 2u 0.1u 0.1u 10u 30u 10) Rser=1u Cpar=100n
.tran 0 100u 0 5n
