Hexmesh of model with multiple fillets

Hello,

 

I was wondering to hexmesh of a model , a part of which is shown in the image attached.(Image 1 Grey)

 

I always find myself in trouble when I have such fillets in the model.

 

Is it possible to make this mappable? I can use pentas upto 5% also. defeaturing is not allowed.

 

Also find attached another image (image 2 Blue). Which has fillets running over entire length of model.

 

What should be the approach for hexmeshing such objects with fillets?

 

Sorry for not sharing model and only the image.

 

Regards,

Bharat
